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
bit 7-1
bit 0
MSK<7:1>: Mask bits
1 = The received address bit n is compared to SSP1ADD<n> to detect I²C address match
0 = The received address bit n is not used to detect I²C address match
MSK<0>: Mask bit for I²C Slave mode, 10-bit Address
I²C Slave mode, 10-bit address (SSP1M<3:0> = 0111 or 1111):
1 = The received address bit 0 is compared to SSP1ADD<0> to detect I²C address match
0 = The received address bit 0 is not used to detect I²C address match I²C Slave mode, 7-bit address,
the bit is ignored

Master mode:
bit 7-0
ADD<7:0>: Baud Rate Clock Divider bits
SCL pin clock period = ((ADD<7:0> + 1) *4)/FOSC
10-Bit Slave mode — Most Significant Address Byte:
bit 7-3
bit 2-1
bit 0
Not used: Unused for Most Significant Address Byte. Bit state of this register is a “don’t care.” Bit
pattern sent by master is fixed by I²C specification and must be equal to ‘11110’. However, those bits
are compared by hardware and are not affected by the value in this register.
ADD<2:1>: Two Most Significant bits of 10-bit address
Not used: Unused in this mode. Bit state is a “don’t care.”
10-Bit Slave mode — Least Significant Address byte:
bit 7-0
ADD<7:0>: Eight Least Significant bits of 10-bit address
7-Bit Slave mode:
bit 7-1
bit 0
ADD<7:1>: 7-bit address
Not used: Unused in this mode. Bit state is a “don’t care.”
