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
Master mode: I²C mode
bit 7-0
Baud Rate Clock Divider bits⁽¹⁾
SCK/SCL pin clock period = ((SSPxADD<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<9:8>: 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
Note 1:
7-bit Slave Address
Not used: Unused in this mode. Bit state is a don’t care.
Values of 0x00, 0x01 and 0x02 are not valid for SSPxADD when used as a Baud Rate Generator for I²C.
This is an implementation limitation.

MSK<7:1>: Mask bits
1 = The received address bit n is compared to SSPxADDn to detect I²C address match
0 = The received address bit n is not used to detect I²C address match
MSK0: Mask bit for I²C Slave mode, 10-bit Address
I²C Slave mode, 10-bit address (SSPM<3:0> = 0111 or 1111):
1 = The received address bit 0 is compared to SSPxADD0 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.
