0: Warnings do not assert TXFAULT
1: Warnings assert TXFAULT
The RXPWR low warning flag does not assert TXFAULT
0: Alarms do not assert TXFAULT
1: Alarms assert TXFAULT
The RXPWR low alarm flag does not assert TXFAULT
0: Warnings flags are latched. They are cleared by reading
the register or toggling TXDISABLE.
1: Warnings flags are not latched., i.e. they are set and reset
with the warning condition. The flags are also cleared by
reading the register or toggling TXDISABLE.
0: Alarms flags are latched. They are cleared by reading the
register or toggling TXDISABLE.
1: Alarms flags are not latched., i.e. they are set and reset
with alarm condition. The flags are also cleared by reading
the register or toggling TXDISABLE.
