Multi-Master IIC Interface (MMIIC)

NOTE:
MMAD[7:1] — Multi-Master Address
MMEXTAD — Multi-Master Expanded Address
bit-0 of the 8-bit calling address is the MMRW bit from the calling master.
These seven bits represent the MMIIC interface’s own specific slave
address when in slave mode, and the calling address when in master
mode. Software must update MMAD[7:1] as the calling address while
entering master mode and restore its own slave address after master
mode is relinquished. This register is cleared as $A0 upon reset.
This bit is set to expand the address of the MMIIC in slave mode.
When set, the MMIIC will acknowledge the following addresses from
a calling master: $MMAD[7:1], 0000000, and 0001100.
Reset clears this bit.
For example, when MMADR is configured as:
The MMIIC module will respond to the calling address:
or the general calling address:
or the calling address:
1 = MMIIC responds to the following calling addresses:
0 = MMIIC responds to address $MMAD[7:1]
