GCEN - General Call Enable bit
In I²C slave mode only
● 1 - Enables interrupt when a general call address (0000h) is received in the SSPSR; and
● 0 - General call address disabled.
ACKSTAT - Acknowledge Status bit
In I²C Master Transmit mode only
● 1 - Acknowledge was not received from slave; and
● 0 - Acknowledge was received from slave.
ACKDT - Acknowledge data bit
