Switching Between Bus Modes
Each time the bus mode controller must switch from one bus mode to another, there is a
one-cycle CPU system clock delay. An extra clock cycle is not required for repeated
access in any of the bus modes; nor is it required when the eZ80F92 device switches to
eZ80
asynchronous nature of these bus protocols, the extra delay does not impact peripheral
communication.
