RX Data FIFO Direct PIO Burst Read Cycle Timing
Please refer to
description of this mode.
Note: A RX Data FIFO direct PIO burst read cycle begins when both nCS and nRD are asserted.
Note: A[1] must toggle, fresh data is supplied each time A[1] toggles.

Table 15.11 RX Data FIFO Direct PIO Burst Read Cycle Timing Values
The cycle ends when either or both nCS and nRD are de-asserted. They may be asserted and
de-asserted in any order.
