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.
Note: The “Data Bus” width is 32 bits with optional support for 16-bit bus widths
Note: A PIO Burst Read cycle begins when both nCS and nRD are asserted. The cycle ends when
