bit 0
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
bit 6
bit 5-2
bit 1
bit 0
GCEN: General Call Enable bit
1 = Enables interrupt when a general call address (0000h) is received in the SSPSR
0 = General call address disabled
ACKSTAT: Acknowledge Status bit
Unused in Slave mode.
ADMSK5:ADMSK2: Slave Address Mask Select bits (5-Bit Address Masking mode)
1 = Masking of corresponding bits of SSPxADD enabled
0 = Masking of corresponding bits of SSPxADD disabled
ADMSK1: Slave Address Least Significant bit(s) Mask Select bit
In 7-Bit Addressing mode:
1 = Masking of SSPxADD<1> only enabled
0 = Masking of SSPxADD<1> only disabled
In 10-Bit Addressing mode:
1 = Masking of SSPxADD<1:0> enabled
0 = Masking of SSPxADD<1:0> disabled
SEN: Stretch Enable bit⁽¹⁾
1 = Clock stretching is enabled for both slave transmit and slave receive (stretch enabled)
0 = Clock stretching is disabled
Note 1: If the I²C module is active, this bit may not be set (no spooling) and the SSPBUF may not be written (or
writes to the SSPxBUF are disabled).

bit 7-0
MSK7:MSK0: Slave Address Mask Select bit
1 = Masking of corresponding bit of SSPxADD enabled
0 = Masking of corresponding bit of SSPxADD disabled
Note 1: This register shares the same SFR address as SSPxADD, and is only addressable in select MSSPx
operating modes. See Section 19.4.3.4 “7-Bit Address Masking Mode” for more details.
2: MSK0 is not used as a mask bit in 7-bit addressing.
