bit7 bit0
bit 7: GCEN: General Call Enable bit (In I
2
C slave mode only)
1 = Enable interrupt when a general call address (0000h) is received in the SSPSR.
0 = General call address disabled.
bit 6: AKSTAT: Acknowledge Status bit (In I
2
C master mode only)
In master transmit mode:
1 = Acknowledge was not received from slave
0 = Acknowledge was received from slave
bit 5: AKDT: Acknowledge Data bit (In I
2
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
bit 4: AKEN: Acknowledge Sequence Enable bit (In I
2
C master mode only).
In master receive mode:
1 = Initiate Acknowledge sequence on SDA and SCL pins, and transmit AKDT data bit. Automatically
cleared by hardware.
0 = Acknowledge sequence idle
bit 3: RCEN: Receive Enable bit (In I
2
C master mode only).
1 = Enables Receive mode for I
2
C
0 = Receive idle
bit 2: PEN: Stop Condition Enable bit (In I
2
C master mode only).
SCK release control
1 = Initiate Stop condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Stop condition idle
bit 1: RSEN: Repeated Start Condition Enabled bit (In I
2
C master mode only)
1 = Initiate Repeated Start condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Repeated Start condition idle.
bit 0: SEN: Start Condition Enabled bit (In I
2
C master mode only)
1 = Initiate Start condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Start condition idle.
Note: For bits AKEN, RCEN, PEN, RSEN, SEN: If the I
2
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).
