AWR1642: How can I check the ACK response from the slave device with I2C communication?

Kensuke

Part Number: AWR1642

Hello,

I set the I2C module to master mode and send the start condition and slave address.

I want to check the ACK response from the slave device at this time, which bit can I check?

Hi,
I understand that it can be checked with the NACK bit in the ICSTR register, correct?

Is it also usable to check the ACK response after sending the start bit and slave address?
