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)

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).
