17. These parameters are measured from the input signal changing, until the output pin goes to a high-impedance state.
18. CY7C140/CY7C141 only.
19. A write operation on Port A, where Port A has priority, leaves the data on Port B’s outputs undisturbed until one access time after one of the following:
Busy/Interrupt Timing
