To compute the Baud Rate Generator reload value, use
Equation 15-1.
EQUATION 15-1:
15.3
The I2CxMSK register (Register 15-3) 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

I2CxBRG Value
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>).
15.3.1
The I2C1 has limited peripheral pin select capability.
The SDA1/SCL1 pins have alternative multiplexing
based on the setting of the I2C1SEL bit. The default
pins are used when the bit is set.
