Equation
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.

I2C1BRG Value
17.4
The I2C1MSK register
address bit positions as “don’t care” for both 7-Bit and
10-Bit Addressing modes. Setting a particular bit
location (= 1) in the I2C1MSK register causes the slave
module to respond, whether the corresponding
address bit value is ‘0’ or ‘1’. For example, when
I2C1MSK is set to ‘00100000’, the slave module will
detect both addresses: ‘0000000’ and ‘00100000’.
To enable address masking, the Intelligent Peripheral
Management Interface (IPMI) must be disabled by
clearing the IPMIEN bit (I2C1CON<11>).
