I am attempting to interface a PC(AT) card to a bus using a motorola 68hc16z microcontroller. The PCMCIA PC card AT specifications require that we have a delay between asserting the card select and putting the address on the bus.(address setup time) secondly, there is a 20nS time delay required between deasserting the card select and readind the pc card. The motorol micro does not have these buitl in delays between the chip selects and the read write pins.
