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.
ACKSTAT
: 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.
ACKDT
: 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.
ACKEN
: 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 ACKDT data bit. Automatically
cleared by hardware.
0
= Acknowledge sequence idle.
RCEN
: Receive Enable bit (In I
2
C master mode only).
1
= Enables Receive mode for I
2
C.
0
= Receive idle.
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 ACKEN, 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).
