Maximum response latency
a. Timing is relative to the rising edge of UPCLK during which WRDS is asserted.
b. Only applies if a write access is preceded by a read access. RDWR may stay low between 2
c. CS may stay low between successive accesses to the same peripheral.
d. Timing is relative to next rising edge after the one during which WRDS is asserted.
e. Timing is relative to the rising edge of UPCLK during which DTACK is asserted.
f. Only applies if a write access is followed by a read access. RDWR may stay low between 2
g. Timing is relative to the rising edge before the one during which DTACK is asserted.
