Parallel Interrupt Vector Register
The value in this register is placed on the data bus, DB[7:0], when SVCACKP* is activated in
response to an active SVCREQP*. See
Receive Data/Status Registers
The Receive Data/Status register serves two purposes. During a serial receive-service acknowledge
for good data, the RDSR provides access to the receive FIFO. The number of characters available
in the FIFO is indicated by the RDCR, and is described in
up to the value in the RDCR, can be read from the FIFO. All internal FIFO pointers are updated by
the on-chip processor.
During a serial receive exception service acknowledge, the RDSR provides both the received
character and the status that caused the exception condition. By definition, a receive exception
service request has only one character available (multiple receive exceptions produce multiple
service requests). The first read from the RDSR provides the exception status, and the second read
