Data Bus
PIO reads can be used to access CSRs or RX Data and RX/TX status FIFOs. In this mode, counters
in the CSRs are latched at the beginning of the read cycle. Read data is valid as indicated in the timing
diagram. PIO reads can be performed using Chip Select (nCS) or Read Enable (nRD). Either or both
of these control signals must go high between cycles for the period specified.
Note: Some registers have restrictions on the timing of back-to-back, write-read and read-read
Note: The “Data Bus” width is 16 bits
Note: A PIO Read cycle begins when both nCS and nRD are asserted. The cycle ends when either
