Basic clock is supplied from a 14.7456MHz ceramic oscillator.
The CPU contains an oscillation circuit from which the basic clock is
internally driven. If the CPU was not operating properly, the signal

Two oscillators are connected to the CKDC8.
The main clock X3 generates 4.19MHz which is used during power
on.
When power is turned off, the CKDC8 goes into the standby mode
and the main clock stops.
The sub-clock X2 generates 32.768KHz which is primarily used to
update the internal RTC (real time clock). During the standby mode, it
keeps oscillating to update the clock and monitoring the power recovery.

In order to prevent memory loss at a time of power off and power
supply failure of the ECR, the power supply condition is monitored at
all times. When a power failure is met, the CPU suspends the execution of the current program and immediately executes the power-off
program to save the data in the CPU registers in the external S-RAM
with the signal
The signal
STOP forced low to prepare for the power-off situation.
STOP is supplied to the CKDC8 as signal RESET to reset
the devices.
