Notes:

WREN is active High, NCS is Active Low.

READ is transparently latched by WREN and NCS being active.

There is no parameter specified for WREN or NCS Inactive to ALE_IP High, since the internal ALE signal is

disabled until after the end of the internal Read or Write Strobe; hence the need for the

wcIalL

parameter.
