6.17.9 Timing Waveforms
The Timing Waveforms don’t contain ALE(GP34 and TS(GP33). If using External Mode to access, TS
pin must keep low. And use ALE(GP34) to do Low Address Byte(GP0) latch. ALE is high active and
pulse width is at least 50ns. Low Address Byte(GP0) must be stable before ALE changes state from
high to low.
