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.

Transmit Slip Positive
The frequency of the transmit clock is less than the frequency of the
transmit system interface working clock based on 1.544 MHz. A frame
will be repeated. After a slip has performed writing of register XC1 is
not necessary.
Transmit Slip Negative
The frequency of the transmit clock is greater than the frequency of
the transmit system interface working clock based on 1.544 MHz. A
frame will be skipped. After a slip has performed writing of register
XC1 is not necessary.
