In this mode, performance is improved by allowing up to 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.
Note: The “Data Bus” width is 16 bits
Note: A PIO Burst Read cycle begins when both nCS and nRD are asserted. The cycle ends when
