Write Signal
Write Signal
Write Timing Selection
(nEHWR: Pin)
In Peripheral mode, this pin selects the write timing.
[ Example: nMUX=H,nEHWR=H ]
Tie to Hi for CPU’s where nCS goes Hi before the write signal goes Hi.
[ Example: nMUX=H,nEHWR=L ]
Tie to Low for CPUs where nCS goes Hi after the write signal goes Hi.
The write signal differs depending on the CPU types.
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.
