bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘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
= Initiate 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
= Initiate 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
= Initiate 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
= Initiate 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).
