PSHT—PCMCIA Strobe Hold Time
This attribute is used to determine when IOWR_B or WE_B are negated during a PCMCIA
write access or when IORD_B or OE_B are negated during a PCMCIA read access handled
by the PCMCIA interface. This helps meet address/data hold time requirements for slow
memories and peripherals.
PSST—PCMCIA Strobe Setup Time
This attribute is used to determine when IOWR_B or WE_B are asserted during a PCMCIA
write access or when IORD_B or OE_B are asserted during a PCMCIA read access handled
by the PCMCIA interface. This helps meet address/setup time requirements for slow
memories and peripherals.
