5.8.6.5.6. I3C Master Request (MR)

If the received IBI ID matches with the dynamic address of any one of the valid entries in the DAT and the received RnW bit is 0, then the response for the received MR is based on the programmed MR response control.

The secondary master role allows the application to either set the MR response control to 0 or 1 individually to accept or reject the MR request respectively.

The application is expected to be always set to 1, the MR response control for the master only. This requirement allows the master to reject any MR request if received unexpectedly from a malfunctioning slave device.
