Datasheet

The write signal differs depending on the CPU type:

nRWM = H: nDS signal at DIR = L

nRWM = L: nWR signal

NOTE: Refer to the AC timing specifications (in another document) for details (setup time, hold time, etc.).

Compare timing specifications for nEHWR=L and nEHWR=H.

1.6.4 Read Timing Selection

(nEHRD/NSTC[1]: Pin)

ƒ Peripheral mode: This pin selects the read timing type.

ƒ Standalone mode: This is NST- carry-output-digit selection NSTC[1].

[ In case of nMUX=H,nEHRD=H ]

Tie to Hi for CPUs with valid address before nCS and the read signal go low.

[Example: nMUX = H and nEHRD = L]

Tie to L for the CPU’s where nCS is enabled and addresses are valid after the read signal goes low.
