Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
GCEN: General Call Enable bit
Unused in Master mode.
bit 6
ACKSTAT: Acknowledge Status bit (Master Transmit mode only)
1 = Acknowledge was not received from slave
0 = Acknowledge was received from slave
bit 5
ACKDT: Acknowledge Data bit (Master Receive mode only)(1)
1 = Not Acknowledged
0 = Acknowledged
bit 4
ACKEN: Acknowledge Sequence Enable bit(2)
1 = Initiates Acknowledge sequence on SDA and SCL pins and transmits ACKDT data bit;
automatically cleared by hardware
0 = Acknowledge sequence is Idle
bit 3
RCEN: Receive Enable bit (Master Receive mode only)(2)
1 = Enables Receive mode for I2C™
0 = Receive is Idle
bit 2
PEN: Stop Condition Enable bit(2)
1 = Initiates Stop condition on SDA and SCL pins; automatically cleared by hardware
0 = Stop condition is Idle
bit 1
RSEN: Repeated Start Condition Enable bit(2)
1 = Initiates Repeated Start condition on SDA and SCL pins; automatically cleared by hardware
0 = Repeated Start condition Idle
bit 0
SEN: Start Condition Enable bit(2)
1 = Initiates Start condition on SDA and SCL pins; automatically cleared by hardware
0 = Start condition Idle
Note 1: The value that will be transmitted when the user initiates an Acknowledge sequence at the end of a receive.
2: If the I2C module is active, these bits may not be set (no spooling) and the SSPBUF may not be written to
(or writes to the SSPBUF are disabled).
