28.9.6 SSPxCON2

MSSP Control Register 2

Note:

The value that will be transmitted when the user initiates an Acknowledge sequence at the end of a receive.
If the I²C module is active, these bits may not be set (no spooling) and the SSPxBUF may not be written (or writes to the SSPxBUF are disabled).
