13.22.6.2 MOSFET Gate Driver to Host dsPIC DSC

A solicited response byte from the MOSFET Gate Driver will always echo the command byte with bit 7 set to ‘0’ (response) and with bit 6 set to ‘1’ for Acknowledged (ACK) or ‘0’ for Not Acknowledged (NACK). The second byte, if required, will be the data for the host command. Any command that causes an error or is not supported will receive a NACK response.

The MOSFET Gate Driver may send unsolicited command messages to the host dsPIC DSC. All messages to the host controller do not require a response from the host controller.
