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
â1â = Bit is set
W = Writable bit
x = Bit is unknown
â0â = Bit is cleared
U = Unimplemented bit, read as â0â
-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 SSPxADD<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 SSPxADD<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 24-6: SSPxADD: MSSPx ADDRESS AND BAUD RATE REGISTER (I2C MODE)

bit 0
Legend:
R = Readable bit
u = Bit is unchanged
â1â = Bit is set
W = Writable bit
x = Bit is unknown
â0â = Bit is cleared
U = Unimplemented bit, read as â0â
-n/n = Value at POR and BOR/Value at all other Resets
Master mode:
bit 7-0
ADD<7:0>: Baud Rate Clock Divider bits
SCLx pin clock period = ((ADD<7:0> + 1) *4)/FOSC
10-Bit Slave mode â 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 âdonât careâ. Bit
pattern sent by master is fixed by I2C specification and must be equal to â11110â. 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 âdonât careâ.
10-Bit Slave mode â 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 âdonât careâ.
