1.
The following external circuit is recommended.
2.
Current to the on-chip pull-down resistor and power-on reset circuit (mask option) is not included.
3.
When the processor clock control register (PCC) is set to 0011 and is operated in the high-speed mode.
4.
When the PCC register is set to 0000 and is operated in the low-speed mode.
5.
When the system clock control register (SCC) is set to 1001 and is operated with the subsystem clock with
main system clock oscillation stopped.
Remarks
Start the power supply smoothly.
