bit 7
GCEN: General Call Enable bit (Slave mode only)
1 = Enable interrupt when a general call address (0000h) is received in the SSPSR
0 = General call address disabled
ACKSTAT: Acknowledge Status bit (Master Transmit mode only)
1 = Acknowledge was not received from slave
0 = Acknowledge was received from slave
ACKDT: Acknowledge Data bit (Master Receive mode only)
1 = Not Acknowledge
0 = Acknowledge
ACKEN: Acknowledge Sequence Enable bit (Master Receive mode only)
1 = Initiate Acknowledge sequence on SDA and SCL pins, and transmit ACKDT data bit.
0 = Acknowledge sequence IDLE
RCEN: Receive Enable bit (Master mode only)
1 = Enables Receive mode for I
0 = Receive IDLE
PEN: STOP Condition Enable bit (Master mode only)
1 = Initiate STOP condition on SDA and SCL pins. Automatically cleared by hardware.
0 = STOP condition IDLE
RSEN: Repeated START Condition Enabled bit (Master mode only)
1 = Initiate Repeated START condition on SDA and SCL pins.
0 = Repeated START condition IDLE
SEN: START Condition Enabled/Stretch Enabled bit
In Master mode:
1 = Initiate START condition on SDA and SCL pins. Automatically cleared by hardware.
0 = START condition IDLE
In Slave mode:
1 = Clock stretching is enabled for both Slave Transmit and Slave Receive (stretch enabled)
0 = Clock stretching is enabled for slave transmit only (Legacy mode)
Legend:
R = Readable bit

Automatically cleared by hardware.
For bits ACKEN, RCEN, PEN, RSEN, SEN: If the I
mode, this bit may not be set (no spooling) and the SSPBUF may not be written (or
writes to the SSPBUF are disabled).
Value that will be transmitted when the user initiates an Acknowledge sequence at
the end of a receive.
