„Interrupts
• 12 sources, 11 vector addresses
1) Provides three levels of multiplex interrupt control. Any interrupt requests of the level equal to or lower than the
current interrupt are not accepted.
2) When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the highest level
takes precedence over the other interrupts. For interrupts of the same level, the interrupt into the smallest vector
address takes precedence.

• The priority level can be specified by three levels.
• Of interrupts of the same level, the one with the smallest vector address takes precedence.
„Subroutine Stack Levels
• Max- whole RAM area (Stack is set in RAM)
„Oscillation Circuits
• OSC1: For system clock
ceramic oscillation with external CGC, CDC or RC oscillation (external RCR1)
• OSC0: For low-speed system clock, base timer count, for LCD display
32kHz crystal oscillation with external CGX, CDX or RC oscillation (external RCR0)
• Internal oscillation circuit: Internal RC
* Depends on control resister for each oscillator operation and stop.
Initial setting - External oscillation stop, internal RC oscillation operation
