DATASHEET
Note:
A PIO Read cycle begins when both nCS and nRD are asserted. The cycle ends when either
or both nCS and nRD are deasserted. They may be asserted and deasserted in any order.
6.3
PIO Burst Reads
In this mode, performance is improved by allowing up to 8, DWORD read cycles, or 16, WORD read
cycles back-to-back. PIO Burst Reads can be performed using Chip Select (nCS) or Read Enable
(nRD). Either or both of these control signals must go high between bursts for the period specified.
Timing for 16-bit and 32-bit PIO Burst Mode Read cycles is identical, with the exception that D[31:16]
are not driven during a 16-bit burst.
