Read Timing Selection
(nEHRD: Pin)
In Peripheral mode, this pin selects the read timing type.
[ 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.
Address acquisition timing in the CircLink delays about 50 ns (with 20 MHz-XTAL).
The read signal differs depending on the CPU type:
nRWM = H: nDS signal at DIR = H
nRWM = L: nRD signal
Refer to the AC timing specifications (in another document) for details (setup time, hold time, etc.).
Compare timing specifications for nEHRD=L and nEHRD=H.
