These clock rate values are for guidance only. The actual clock rate can be affected by various system
level parameters. The actual clock rate should be measured in its intended application.
The address bits listed here will never cause an address match, independent of 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
15.4
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
module to respond whether the corresponding address
bit value is a ‘0’ or a ‘1’. For example, when I2CxMSK
is set to ‘00010000’, the slave module will detect both
addresses, ‘0000000’ and ‘0010000’.
To enable address masking, the IPMI (Intelligent
Peripheral Management Interface) must be disabled by
clearing the IPMIEN bit (I2CxCON<11>).
Note:

Slave Address Masking
As a result of changes in the I
col, the addresses in Table 15-2 are
reserved and will not be acknowledged in
Slave mode. This includes any address
mask settings that include any of these
addresses.
