Symbol
A change in at least one of the M4 Bits will be passed via
MON-2 only after valid triple last look.
This is the default setting after reset in all non repeater
modes
A change in at least one of the M4 Bits will be passed via
MON-2 only if the CRC is valid for the last two superframes,
not including the current one.
This is the default setting after reset in the repeater modes
A change in at least one of the M4 Bits will be passed via
MON-2 only after valid triple last look, and if the CRC is valid
for the last two superframes, not including the current one
Every change in at least one of the M4 Bits will be passed
via MON-2
