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.

[6.1.3] - 2024-09-27
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
- M8PD-7588 :- Fixed PIC18 I2C drivers to check the host read event only once after the address match
- M8PD-5191 :- Fixed the I2C address mask for PIC18F devices to be set to default POR of "7F" to avoid I2C slave malfunctioning with multiple devices
New Features and Improvements
- M8PD-7530 :- Fixed MISRA violations for I2C/TWI firmware
