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 Acknowledge
0 = Acknowledge
bit 4
ACKEN: Acknowledge Sequence Enable bit⁽²⁾
1 = Initiates Acknowledge sequence on SDAx and SCLx pins and transmit ACKDT data bit.
Automatically cleared by hardware.
0 = Acknowledge sequence Idle
bit 3
RCEN: Receive Enable bit (Master Receive mode only)⁽²⁾
1 = Enables Receive mode for I²C
0 = Receive Idle
bit 2
PEN: Stop Condition Enable bit⁽²⁾
1 = Initiates Stop condition on SDAx and SCLx pins. Automatically cleared by hardware.
0 = Stop condition Idle
bit 1
RSEN: Repeated Start Condition Enable bit⁽²⁾
1 = Initiates Repeated Start condition on SDAx and SCLx pins. Automatically cleared by hardware.
0 = Repeated Start condition Idle
bit 0
SEN: Start Condition Enable bit⁽²⁾
1 = Initiates Start condition on SDAx and SCLx pins. Automatically cleared by hardware.
0 = Start condition Idle
Note 1: 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 SSPxBUF may not be written
(or writes to the SSPxBUF are disabled).
