Multi-Master IIC Interface (MMIIC)
14.5.1 Multi-Master IIC Address Register (MMADR)

Address:
MMAD[7:1] — Multi-Master Address
MMEXTAD — Multi-Master Expanded Address

Write:
These 7 bits can be the MMIIC interface’s own specific slave address
in slave mode or the calling address when in master mode. Reset sets
a default value of $A0.
This bit is set to expand the calling address of the MMIIC in slave
mode. When set, the MMIIC will acknowledge the general call
address $00 and the matched 4-bit MSB address, MMAD[7:4].
For example, when MMAD[7:1] = $A1 and MMEXTAD = 1, the MMIIC
calling address is $A0, and it will acknowledge calling addresses $00
and $A0 to $AF.
Reset clears this bit.

1 = MMIIC calling address is $MMAD[7:4]0
0 = MMIIC address is $MMAD[7:1]
