bit 7:
bit 6:
GCEN: General Call Enable bit (In I C slave mode only)
1 = Enable interrupt when a general call address (0000h) is received in the SSPSR.
0 = General call address disabled.
2
ACKSTAT: Acknowledge Status bit (In I C master mode only)
In master transmit mode:
1 = Acknowledge was not received from slave
0 = Acknowledge was received from slave
2
bit 5:
bit 4:
ACKDT: Acknowledge Data bit (In I C master mode only)
In master receive mode:
Value that will be transmitted when the user initiates an Acknowledge sequence at the end of a receive.
1 = Not Acknowledge
0 = Acknowledge
2
ACKEN: Acknowledge Sequence Enable bit (In I C master mode only).
In master receive mode:
1 = Initiate Acknowledge sequence on SDA and SCL pins, and transmit ACKDT data bit. Automatically
cleared by hardware.
0 = Acknowledge sequence idle
2
bit 3:
RCEN: Receive Enable bit (In I C master mode only).
2
1 = Enables Receive mode for I C
0 = Receive idle
2
bit 2:
PEN: Stop Condition Enable bit (In I C master mode only).
SCK release control
1 = Initiate Stop condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Stop condition idle
2
bit 1: RSEN: Repeated Start Condition Enabled bit (In I C master mode only)
1 = Initiate Repeated Start condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Repeated Start condition idle.
2
bit 0: SEN: Start Condition Enabled bit (In I C master mode only)
1 = Initiate Start condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Start condition idle.
2
Note: For bits ACKEN, RCEN, PEN, RSEN, SEN: If the I C module is not in the idle mode, this bit may not
be set (no spooling), and the SSPBUF may not be written (or writes to the SSPBUF are disabled).
