Register : ic_clr_tx_abrt

Description

Name: Clear TX_ABRT Interrupt Register

Size: 1 bit

Address Offset: 0x54

Read/Write Access: Read

Register Layout

Bits Access Reset Description
[0] R 0x0 ALT_I2C_CLR_TX_ABRT_CLR_TX_ABT
[31:1] ??? 0x0 UNDEFINED

Field : clr_tx_abort

Read this register to clear the TX_ABRT

interrupt (bit 6) of the IC_RAW_INTR_STAT register,

and the IC_TX_ABRT_SOURCE register.

This also releases the TX FIFO from the flushed/reset

state, allowing more writes to the TX FIFO.

Refer to Bit 9 of the IC_TX_ABRT_SOURCE register for

an exception to clearing IC_TX_ABRT_SOURCE.

Reset value: 0x0

struct ALT_I2C_CLR_TX_ABRT_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
