Interrupt Status Register 4 (Read)
ISR4
All bits are reset when ISR4 is read.
If bit GCR.VIS is set to ‘1’, interrupt statuses in ISR4 may be flagged although they are
masked via register IMR4. However, these masked interrupt statuses neither generate a
signal on INT, nor are visible in register GIS.

Remote Alarm TS 16 Status Change
A change in the remote alarm bit in CAS multiframe alignment word
is detected.
Receive Slip Negative
The frequency of the receive route clock is greater than the frequency
of the receive system interface working clock based on 2.048 MHz. A
frame will be skipped. It will be set during alarm simulation.
Receive Slip Positive
The frequency of the receive route clock is less than the frequency of
the receive system interface working clock based on 2.048 MHz. A
frame will be repeated. It will be set during alarm simulation.
Transmit Slip Positive
The frequency of the transmit clock is less than the frequency of the
transmit system interface working clock based on 2.048 MHz. A frame
will be repeated.
Transmit Slip Negative
The frequency of the transmit clock is greater than the frequency of
the transmit system interface working clock based on 2.048 MHz. A
frame will be skipped.
