The PAL equations and circuits presented here are not intended to be the
optimal implementation for every system. Depending on the CPU's clock
frequency, memory access times, and system architecture, different circuits
The MC68030 is capable of running three types of external bus cycles as
determined by the cyc!e termination and handshake signals (refer to SECTION
7 BUS OPERATION). These three types of bus cycles are:

3. Burst operation cycles, terminated by the STERM and CBACK signals,
2. Synchronous cycles, terminated by the STERM signal, have a minimum
