Function
Address bus
Data bus
Bus cycle start
Asserted when a normal space, burst ROM (clock
synchronous/asynchronous), or PCMCIA is accessed. Asserted by
the same timing as CAS in SDRAM access.
Chip select
Chip select
Active only for address map 1
Corresponds to PCMCIA card select signals D15 to D8 when the
