Bit 9: Port Status Register Interrupt Status (PSR) This bit is set when any of the latched status register bits, that
are enabled for interrupt, in the PORT.SRL register are set. The interrupt pin will be driven when this bit is set and
the corresponding GL.ISRIE.PISRIE[4:1] is set.
bits, that are enabled for interrupt, in the B3ZS/HDB3 Line Encoder/Decoder block are set. The interrupt pin will be
driven when this bit is set and the corresponding GL.ISRIE.PISRIE[4:1] is set.
Bit 7: Trail Trace Status Register Interrupt Status (TTSR) This bit is set when any of the latched status register
bits, that are enabled for interrupt, in the trail trace block are set. The interrupt pin will be driven when this bit is set
and the corresponding GL.ISRIE.PISRIE[4:1] is set.
Bit 6: FEAC Status Register Interrupt Status (FSR) This bit is set when any of the latched status register bits,
that are enabled for interrupt, in the FEAC block are set. The interrupt pin will be driven when this bit is set and the
corresponding GL.ISRIE.PISRIE[4:1] is set.
Bit 5: HDLC Status Register Interrupt Status (HSR) This bit is set when any of the latched status register bits,
that are enabled for interrupt, in the HDLC block are set. The interrupt pin will be driven when this bit is set and the
corresponding GL.ISRIE.PISRIE[4:1] is set.
Bit 4: BERT Status Register Interrupt Status (BSR) This bit is set when any of the latched status register bits,
that are enabled for interrupt, in the BERT block are set. The interrupt pin will be driven when this bit is set and the
corresponding GL.ISRIE.PISRIE[4:1] is set.
Bit 0: Framer Status Register Interrupt Status (FMSR) This bit is set when any of the latched status register bits,
that are enabled for interrupt, in the active DS3 or E3 framer block are set. The interrupt pin will be driven when this
bit is set and the corresponding GL.ISRIE.PISRIE[4:1] is set.
Bit 8: Line Code Status Register Interrupt Status (LCSR) This bit is set when any of the latched status register
