Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
HC = Cleared by hardware S = User set
bit 7
GCEN: General Call Enable bit (in I²C Slave mode only)
1 = Enable interrupt when a general call address (0x00 or 00h) is received in the SSP1SR
0 = General call address disabled
bit 6
ACKSTAT: Acknowledge Status bit (in I²C mode only)
1 = Acknowledge was not received
0 = Acknowledge was received
bit 5
ACKDT: Acknowledge Data bit (in I²C mode only)
In Receive mode:
Value transmitted when the user initiates an Acknowledge sequence at the end of a receive
1 = Not Acknowledge
0 = Acknowledge
bit 4
ACKEN: Acknowledge Sequence Enable bit (in I²C 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
bit 3
RCEN: Receive Enable bit (in I²C Master mode only)
1 = Enables Receive mode for I²C
0 = Receive idle
bit 2
PEN: Stop Condition Enable bit (in I²C 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 I²C 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 I²C Master mode only)
In Master mode:
1 = Initiate Start condition on SDA and SCL pins. Automatically cleared by hardware.
0 = Start condition Idle
In Slave mode:
1 = Clock stretching is enabled for both slave transmit and slave receive (stretch enabled)
0 = Clock stretching is disabled
Note 1: For bits ACKEN, RCEN, PEN, RSEN, SEN: If the I²C module is not in the Idle mode, this bit may not be
set (no spooling) and the SSP1BUF may not be written (or writes to the SSP1BUF are disabled).
