13.12.3
An SSP Mask (SSPMSK) register is available in I
Slave mode as a mask for the value held in the
SSPSR register during an address comparison
operation. A zero (‘0’) bit in the SSPMSK register has
the effect of making the corresponding bit in the
SSPSR register a ‘don’t care’.
This register is reset to all ‘1’s upon any Reset
condition and, therefore, has no effect on standard
SSP operation until written with a mask value.

the SSPMSK register.

This register must be initiated prior to setting
SSPM<3:0> bits to select the I
10-bit address).
This register can only be accessed when the appropriate
mode is selected by bits (SSPM<3:0> of SSPCON).
The SSP Mask register is active during:
• 7-bit Address mode: address compare of A<7:1>.
• 10-bit Address mode: address compare of A<7:0>
only. The SSP mask has no effect during the
reception of the first (high) byte of the address.
