NOTE FOR SUPPLYING POWER
(1) Timing of power supplying to AC pin
The internal circuit of M35061-XXXSP/FP is reset when the level
of the auto clear input pin AC is “L”.
This pin is hysteresis input with the pull-up resistor. The timing
about power supplying of AC pin is shown in Figure 18.
After supplying the power (VDD and VSS) to M35061-XXXSP/FP,
the tW time must be reserved for 1 ms or more.
Before starting input from the microcomputer, the waiting time
(tS) must be reserved for 200 ms after the supply voltage to the
AC pin becomes 0.8 VDD or more.
(2) Timing of power supplying to VDD1 pin and VDD2 pin
The power need to supply to VDD1 and VDD2 at a time, though it
is separated perfectly between the VDD1 as the digital line and
the VDD2 as the analog line.

PRECAUTION FOR USE
Notes on noise and latch-up
In order to avoid noise and latch-up, connect a bypass capacitor
(0.1F) directly between the VDD1 pin and VSS pin, and the VDD2 pin
and VSS pin using a heavy wire.
