8.5.5 Timing in the Asynchronous Motorola-Mode (for example, 68HC16) :

In the asynchronous Motorola mode, the SPC3 acts like memory with Ready logic, whereby the access times depend on the type of accesses.

The request for an access of SPC3 is generated from the positive edge of the AS signal (in addition: XCS=´0´, R_W=´1´). The request for a write accessi generated from the positive edge of the AS signal (in addition: XCS=´0´, R_W=´0´).
