I2C Driver

Overview

The Inter-Integrated Circuit (I2C) bus is a multi-host serial data communication bus. Devices communicate in a host/ client environment where the host devices initiate the communication. A client device is controlled through addressing.

Bug Fixes

• M8PD-9373 :- Included stddef.h header in the interface files of the I2C/TWI Host and client for successful compilation
• M8PD-8902 :- Fixed I2C drivers to avoid incorrect occurrence of TX_READY state prior to the ACK reception for the address match
• M8PD-8843 :- Fixed I2C drivers to enable clock stretching for ack, address or data reception
