AM263P4-Q1: Integration of MCP7940N(RTC IC) into AM263Px CC through I2C Communication

Tool/software:

Hi,

    I am currently working with the AM263Px Control Card using MCU+SDK version 10.01.00.31, integrating it with the MCP7940N RTC IC from Microchip via I2C communication. I have successfully established communication between the two devices.

However, during data transmission from the AM263Px to the MCP7940N, the SCL line remains low (logic '0') after the successful transmission of three bytes (Register address byte followed ny two data bytes).

For your reference, I have attached a logic analyzer capture.

Regards,

Tarun
