An Interrupt Status register (ISR) bit is latched active (high) whenever its corresponding
interrupt source [ALARM; addr n5] reports an interrupt event. All latched ISR bits are cleared
when ISR is read. If the corresponding interrupt enable [IER; addr n7] is active (high), each
interrupt event forces the IRQ output pin active (low).
ISR reports an interrupt event when an alarm status [ALARM; addr n5] changes from inactive to
active (rising edge) or from active to inactive (falling edge). The associated real-time alarm
status must be read to determine the current alarm state.
Receive Analog Loss of Signal—Indicates receiver analog loss of signal status change.
Receive Loss of Signal—Indicates receiver loss of signal status change.
Transmit Loss of Clock—Indicates transmitter loss of clock status change.
Transmit Loss of Signal—Indicates transmitter output signal fault status change.
Transmit Short Circuit—Indicates transmitter loss of analog signal status change.
Jitter Attenuator Error— Indicates JAT FIFO empty/full status change.
Bipolar Violation— Indicates a non-zero code bipolar violation status change.
