mode, the X1 pin stops when “H” is input in STOP mode. To prevent one output from competing against another,
an external resistor of about 1 k
should be provided.
The following figure shows an example usage of an external clock.

Care During Powering Up
When powering up
When turning on the power supply, never fail to start from setting the RST pin to “L” level. And after the power
supply voltage goes to VCC level, at least after ensuring the time for 5 machine cycle, then set to “H” level.
Source oscillation input
At turning on the power supply, never fail to input the clock before cancellation of the oscillation stabilizing
waiting.
Power on resetting
When powering up or when turning the power back on after the supply voltage drops below the operation
assurance range, be sure to reset the power.
Power on sequence
Turn on the power in the order of VCC, AVCC and AVRH. The power should be disconnected in inverse order.
Even when an AD converter is not in use, connect AVCC to the VCC level and AVSS to the VSS level.
Even when a DA converter is not in use, connect DAVC to the VCC level and DAVS to the VSS level.

When the Clock Function (Calendar Macro) Is Not in Use
Not using the clock function, the clock oscillation pin must be configured as shown below.
