DS3161/DS3162/DS3163/DS3164
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
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
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
Bit 3: System FIFO Status Register Interrupt Status (SFSR) This bit is set when any of the latched status
register bits, that are enabled for interrupt, in either the transmit or receive FIFO 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 2: Cell/Packet Status Register Interrupt Status (CPSR) This bit is set when any of the latched status register
bits, that are enabled for interrupt, in the active transmit or receive cell processor or packet processor 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 1: PLCP Status Register Interrupt Status (PPSR) This bit is set when any of the latched status register bits,
that are enabled for interrupt, in the active PLCP block are set. The interrupt pin will be driven when this bit 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 0: Performance Monitoring Update Status (PMS) This bits indicates the status of all active performance
monitoring register and counter update signals in this port. It is an “AND” of all update status bits and is not set until
all performance registers are updated and the counters reset. In software update modes, the update request bit
PORT.CR1.PMU should be held high until this status bit goes high.
0 = The associated update request signal is low
1 = The requested performance register updates are all completed
