MMAD[7:1] — Multi-Master Address
MMEXTAD — Multi-Master Expanded Address
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:
Note that bit-0 of the 8-bit calling address is the MMRW bit from the
calling master.
