R/W-1/1 R/W-1/1
MSK<7:0>
R/W-1/1
R/W-1/1
R/W-1/1
bit 0
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 SSPADD<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 (SSPM<3:0> = 0111 or 1111):
1 = The received address bit 0 is compared to SSPADD<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.
REGISTER 20-6: SSPADD: MSSP ADDRESS AND BAUD RATE REGISTER (I2C MODE)

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 pat-
tern 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”.
