RF5C296/RF5C396L/RB5C396/RF5C396
Symbol
For the RF5C296 and the RF5C396, the relation between the Read/Write timings for the DATA and ADDRESS sig-
nals and those for the CIOWR#, CIORD#, WE#, and OE# signals is not specified, and dependent on the input timings
for the relevant signals from the system bus and on the internal delay time of the named signals.
It is recommended that the above should be included in the considerations of timing conditions for the JEIDA4.2 (or
PCMCIA2.1) system.
