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):
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
All other SSP modes: this bit has no effect.

Legend:
Note 1:
2:
x = unknown, u = unchanged, - = unimplemented locations read as ‘0’. Shaded cells are not used by SSP
module in I2C mode.
Maintain these bits clear in I2C mode.
Accessible only when SSPM<3:0> = 1001.
