Address Sampling
Address Sampling
The write signal differs depending on the CPU type:
nRWM = H: nDS signal at DIR = L
nRWM = L: nWR signal
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.
Read Timing Selection
(nEHRD/NSTC[1]: Pin)
[ 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.
