The address bits listed here will never cause an address match, independent of the address mask settings.
Address will be Acknowledged only if GCEN = 1.
Match on this address can only occur on the upper byte in 10-Bit Addressing mode.

I2CxBRG Value
16.4
The I2CxMSK register (Register 16-3) designates
address bit positions as “don’t care” for both 7-Bit and
10-Bit Addressing modes. Setting a particular bit loca-
tion (= 1) in the I2CxMSK register causes the slave
module to respond whether the corresponding address
bit value is a ‘0’ or a ‘1’. For example, when I2CxMSK
is set to ‘00100000’, the slave module will detect both
addresses, ‘0000000’ and ‘00100000’.
To enable address masking, the IPMI (Intelligent
Peripheral Management Interface) must be disabled by
clearing the IPMIEN bit (I2CxCON<11>).
Description

Slave Address Masking
As a result of changes in the I
col, the addresses in Table 16-2 are
reserved and will not be Acknowledged in
Slave mode. This includes any address
mask settings that include any of these
addresses.
