13.5.11 Aperiodic Status Register (PASR)
All bits in this register are read only and are set on hardware or software reset.
The PASR register is a 16-bit register containing the aperiodic interrupt status information for the C/I and
monitor channel transmit and receive registers for all four ports on the MCF5272. An aperiodic interrupt
condition remains asserted as long as any one of the bits within the PASR register is set.

D receive data full. This bit indicates that the D receive data register for the respective port is full.
DRDF is cleared when the CPU reads the receive data register PnDRR.
B2 receive data full. This bit indicates that the B2 receive data register for the respective port is full.
B2RDF is cleared when the CPU reads the receive data register PnB2RR.
B1 receive data full. This bit indicates that the B1 receive data register for the respective port is full.
B1RDF is cleared when the CPU reads the receive data register PnB2RR.

GCI C/I received. When set, this bit indicates that valid new data has been written to a GCI C/I
receive register. An interrupt is queued when this bit is set if the GCR interrupt enable bit has
been set in the corresponding PnICR register. The GCR bit and associated interrupt are
automatically cleared when the corresponding PnGCIR register has been read by the CPU.
GCI C/I transmitted. When set, this bit indicates that a C/I register is empty. An interrupt is
queued when this bit is set if the GCT interrupt enable bit has been set in the corresponding
PnICR register. The GCT bit and associated interrupt are automatically cleared when the
PGCITSR register has been read by the CPU.
GCI monitor received. When set, this bit indicates that data has been written to a monitor
channel receive register. An interrupt is queued when this bit is set if the GMR interrupt enable
bit has been set in the corresponding PnICR register. The GMR bit and associated interrupt are
automatically cleared when the corresponding PnGMR register has been read by the CPU.
GCI monitor transmitted. When set, this bit indicates that the monitor channel transmit register
is empty. An interrupt is queued when this bit is set if the GMT interrupt enable bit has been set
in the corresponding PnICR register. The GMT bit and associated interrupt are automatically
cleared when the PGMTS register has been read by the CPU.
