MSPM0G1107: Regarding RW bit information

Hello experts,

In I2C communication (slave), the slave address match check is performed by the driver API, the MSPM0G1X0X_G3X0X Driver Library, but I would like to know how to obtain the RW bit information that is notified at the same time. Could you please tell me if there is any API to obtain RW bit information?

Hi,

There is two bits in register TSR.TREQ and TSR.RREQ for transmit or receive status check. But I do not find any APIs to check it.

Best regards,

Thank you for your reply.

Since TSR.TREQ and TSR.RREQ did not appear to be included in the latest SDK 2.05.01.00 as of July 29, we are attempting to read using SLAVE.SSR.
Please tell me the read timing of SLAVE.SSR.
Will the value be the same of when it is read between the start condition and the stop condition?

Also, from which SDK version will TSR.TREQ and TSR.RREQ be included?

Best regards,
Yoshito Goto

Hi,

The SLAVE.SSR also works. The TSR.TREQ and TSR.RREQ are the same as SLAVE.SSR

Best regards,
