WIS_EXT_ALARM
WIS_EXT_ALARM is used to indicate that a WAN-related fault has occurred on the receive path.
WIS_EXT_ALARM is the bitwise OR of the WIS Extended Alarms Status Register bits in register 2.C502h.
WIS_EXT_ALARM can be programmed to assert only when specific receive path fault conditions are present. The
programming is performed by writing to a mask register at address 2.C501h. The contents of register 2.C502h is
AND’ed with register 2.C501h prior to application of the OR function to generate the WIS_ALARM signal.
tWIS_ALARM = {OR of (reg 2.C501h.n ‘bit wise AND’ reg 2.C502.n) for n=0..11}
