0x00
Read/write
This 8-bit MMR is used with hardware general
calls when I2CxSCON Bit 3 is set to 1. This
register is used in cases where a master is unable
to generate an address for a slave, and instead, the
slave must generate the address for the master.

0xFFFF093C = I2C1ID0
0xFFFF083C = I2C0ID0

0x00
Read/write
These 8-bit MMRs are programmed with I
bus IDs of the slave. See the I2C Bus Addresses
section for further details.

These 16-bit MMRs contain the status of the
Rx/Tx FIFOs in both master and slave modes.
