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.
0000= Strobe negation to Address change 0 clocks.
0001= Strobe negation to Address change 1 clock.
0010= Strobe negation to Address change 2 clocks.
0011= Strobe negation to Address change 3 clocks.
0100= Strobe negation to Address change 4 clocks.
0101= Strobe negation to Address change 5 clocks.
0110= Strobe negation to Address change 6 clocks.
0111= Strobe negation to Address change 7 clocks.
1000= Strobe negation to Address change 8 clocks.
1001= Strobe negation to Address change 9 clocks.
1010= Strobe negation to Address change 10 clocks.
1011= Strobe negation to Address change 11 clocks.
1100= Strobe negation to Address change 12 clocks.
1101= Strobe negation to Address change 13 clocks.
1110= Strobe negation to Address change 14 clocks.
1111= Strobe negation to Address change 15 clocks.
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.
0000= Reserved.
0001= Address to Strobe assertion 1 clock cycle.
0010= Address to Strobe assertion 2 clock cycles.
0011= Address to Strobe assertion 3 clock cycles.
0100= Address to Strobe assertion 4 clock cycles.
0101= Address to Strobe assertion 5 clock cycles.
0110= Address to Strobe assertion 6 clock cycles.
0111= Address to Strobe assertion 7 clock cycles.
1000= Address to Strobe assertion 8 clock cycles.
1001= Address to Strobe assertion 9 clock cycles.
1010= Address to Strobe assertion 10 clock cycles.
1011= Address to Strobe assertion 11 clock cycles.
1100= Address to Strobe assertion 12 clock cycles.
1101= Address to Strobe assertion 13 clock cycles.
1110= Address to Strobe assertion 14 clock cycles.
1111= Address to Strobe assertion 15 clock cycles.
