Note:
1. The cycle time can be extended by integer multiples of the clock period (27 ns at 36 MHz, 54 ns at 18.432 MHz, and
77 ns at 13 MHz), by either driving EXPRDY low and/or by programming a number of wait states. EXPRDY is sampled on
the falling edge of EXPCLK before the data transfer. If low at this point, the transfer is delayed by one clock period where
EXPRDY is sampled again. EXPCLK need not be referenced when driving EXPRDY, but is shown for clarity.
