Register : ic_intr_stat

Description

Name: I2C Interrupt Status Register

Size: 14 bits

Address Offset: 0x2C

Read/Write Access: Read

Each bit in this register has a corresponding mask bit

in the IC_INTR_MASK register. These bits are cleared by reading the matching

interrupt clear register. The unmasked raw versions of these bits are

available in the IC_RAW_INTR_STAT register.

Field : r_rx_under

Set if the processor attempts to read the receive buffer when it is empty by

reading from the IC_DATA_CMD register. If the module is disabled

(IC_ENABLE[0]=0), this bit keeps its level until the master or slave state

machines go into idle, and when ic_en goes to 0, this interrupt is cleared.

Field : r_rx_over

Set if the receive buffer is completely filled to IC_RX_BUFFER_DEPTH and

an additional byte is received from an external I2C device. The DW_apb_i2c

acknowledges this, but any data bytes received after the FIFO is full are lost. If

the module is disabled (IC_ENABLE[0]=0), this bit keeps its level until the

master or slave state machines go into idle, and when ic_en goes to 0, this

interrupt is cleared.

NOTE: If the parameter IC_RX_FULL_HLD_BUS_EN=1, then the RX_OVER interrupt is

never set to 1, because the criteria to set this interrupt are never met.

Field : r_rx_full

Set when the receive buffer reaches or goes above the RX_TL threshold in the

IC_RX_TL register. It is automatically cleared by hardware when buffer level

goes below the threshold. If the module is disabled (IC_ENABLE[0]=0), the

RX FIFO is flushed and held in reset; therefore the RX FIFO is not full. So this

bit is cleared once the IC_ENABLE bit 0 is programmed with a 0, regardless of

the activity that continues.

Field : r_tx_over

Set during transmit if the transmit buffer is filled to IC_TX_BUFFER_DEPTH

and the processor attempts to issue another I2C command by writing to the

IC_DATA_CMD register. When the module is disabled, this bit keeps its level

until the master or slave state machines go into idle, and when ic_en goes to 0,

this interrupt is cleared.

Field : r_tx_empty

The behavior of the TX_EMPTY interrupt status differs based on the

TX_EMPTY_CTRL selection in the IC_CON register.

When TX_EMPTY_CTRL = 0: This bit is set to 1 when the transmit buffer is at or below the threshold

value set in the IC_TX_TL register.

When TX_EMPTY_CTRL = 1: This bit is set to 1 when the transmit buffer is at or below the threshold

value set in the IC_TX_TL register and the transmission of the

address/data from the internal shift register for the most recently popped

command is completed.

It is automatically cleared by hardware when the buffer level goes above the

threshold. When IC_ENABLE[0] is set to 0, the TX FIFO is flushed and held in

reset. There the TX FIFO looks like it has no data within it, so this bit is set

to 1, provided there is activity in the master or slave state machines. When

there is no longer any activity, then with ic_en=0, this bit is set to 0.

Field : r_rd_req

This bit is set to 1 when DW_apb_i2c is acting as a slave and another I2C

master is attempting to read data from DW_apb_i2c. The DW_apb_i2c holds

the I2C bus in a wait state (SCL=0) until this interrupt is serviced, which means

that the slave has been addressed by a remote master that is asking for data to

be transferred. The processor must respond to this interrupt and then write the

requested data to the IC_DATA_CMD register. This bit is set to 0 just after the

processor reads the IC_CLR_RD_REQ register.

#define ALT_I2C_INTR_STAT_R_RD_REQ_SET(value)   (((value) << 5) & 0x00000020)
 

Field : r_tx_abrt

This bit indicates if DW_apb_i2c, as an I2C transmitter,

is unable to complete the intended actions on the

contents of the transmit FIFO. This situation can

occur both as an I2C master or an I2C slave, and is

referred to as a 'transmit abort'.

When this bit is set to 1, the IC_TX_ABRT_SOURCE register

indicates the reason why the transmit abort takes places.

NOTE: The DW_apb_i2c flushes/resets/empties the TX FIFO whenever this

bit is set. The TX FIFO remains in this flushed state until the register

IC_CLR_TX_ABRT is read. Once this read is performed, the TX FIFO is then

ready to accept more data bytes from the APB interface.

Field : r_rx_done

When the DW_apb_i2c is acting as a slave-transmitter,

this bit is set to 1 if the master does not acknowledge

a transmitted byte. This occurs on the last byte of

the transmission, indicating that the transmission is done.

Field : r_activity

This bit captures DW_apb_i2c activity and stays set until it is cleared. There

are four ways to clear it:

  • Disabling the DW_apb_i2c
  • Reading the IC_CLR_ACTIVITY register
  • Reading the IC_CLR_INTR register
  • System reset

Once this bit is set, it stays set unless one of the four methods is used to clear it.

Even if the DW_apb_i2c module is idle, this bit remains set until cleared,

indicating that there was activity on the bus.

Field : r_stop_det

The behavior of the STOP_DET interrupt status differs based on the

STOP_DET_IFADDRESSED selection in the IC_CON register

When STOP_DET_IFADDRESSED =0 : Indicates whether a STOP condition has occurred on the I2C interface

regardless of whether DW_apb_i2c is operating in slave or master mode.

In slave mode, a STOP_DET interrupt is generated irrespective of whether

the slave is addressed or not.

When STOP_DET_IFADDRESSED = 1 :

In Master Mode (MASTER_MODE = 1'b1), indicates a STOP condition has occured on the I2C interface.

In Slave Mode (MASTER_MODE = 1'b0),STOP_DET interrupt is generated only if the slave is addressed.

NOTE: During a general call address, this slave does not issue a STOP_DET

interrupt if STOP_DET_IFADDRESSED=1'b1, even if the slave responds to

the general call address by generating ACK. The STOP_DET interrupt is

generated only when the transmitted address matches the slave address

(SAR).

interface regardless of whether DW_apb_i2c is operating in slave or master

mode.

Field : r_gen_call

Set only when a General Call address is received and it is acknowledged. It

stays set until it is cleared either by disabling DW_apb_i2c or when the CPU

reads bit 0 of the IC_CLR_GEN_CALL register. DW_apb_i2c stores the

received data in the Rx buffer.
