GCEN: General Call Enable bit (In I
1 = Enable interrupt when a general call address (0000h) is received in the SSPSR.
0 = General call address disabled.
ACKSTAT: Acknowledge Status bit (In I
In Master Transmit mode:
1 = Acknowledge was not received from slave
0 = Acknowledge was received from slave
ACKDT: Acknowledge Data bit (In I
In Master Receive mode:
Value that will be transmitted when the user initiates an Acknowledge sequence at the end of
1 = Not Acknowledge (NACK)
0 = Acknowledge (ACK)
ACKEN: Acknowledge Sequence Enable bit (In I
In Master Receive mode:
1 = Initiate Acknowledge sequence on SDA and SCL pins, and transmit ACKDT data bit.
0 = Acknowledge sequence IDLE
RCEN: Receive Enable bit (In I
1 = Enables Receive mode for I
0 = Receive IDLE
