Register Structure

Status/Counter Registers
(continued)
Remote End Alarm Register (SR2)
A bit set to 1 indicates the receive framer is receiving or has recently received the given alarm. Interrupts from this
register are generated once at the onset of the alarm condition. If the alarm is still present at the time of the read,
the bit will remain in the 1 state for the duration of the alarm condition. If the alarm condition is no longer present at
the time of the read, the bit is cleared on read.
