Register : ic_clr_intr

Description

Name: Clear Combined and Individual Interrupt Register

Size: 1 bit

Address Offset: 0x40

Read/Write Access: Read

Register Layout

Bits Access Reset Description
[0] R 0x0 ALT_I2C_CLR_INTR_CLR_INTR
[31:1] ??? 0x0 UNDEFINED

Field : clr_intr

Read this register to clear the combined interrupt,

all individual interrupts, and the IC_TX_ABRT_SOURCE register.

This bit does not clear hardware clearable interrupts but software

clearable interrupts. Refer to Bit 9 of the IC_TX_ABRT_SOURCE register

for an exception to clearing IC_TX_ABRT_SOURCE.

Reset value: 0x0

Data Structure Documentation

struct ALT_I2C_CLR_INTR_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.
