Timing of Data Loading from E
2PROM and Timer Action
The example of timing chart of data loading from the E
2PROM and timer action is shown in Figure 19 and 20.
Set VCCH
≥ 2.5 V when rising VCCH and TIMEN simultaneously.
Signal of low power

DO3 pin
(When E
2PROM
CTR3 = 0)
TIMEN pin
Start of timer action by Write in

A period to define data is; the loading period from E
2PROM + the period to stabilize output from DO7 to 0 pin = within
100
μs.
