Note 1: Vector addressed contain internal jump destination addresses.

2: Reset function in the same way as an interrupt with the highest priority.

3: Key-on wakeup interrupt and UART1 bus collision detection interrupt can be enabled by setting of interrupt source set register. The occurrence of

these interrupts are discriminated by interrupt source discrimination register.

4: A/D conversion interrupt and Timer 1 interrupt can be enabled by setting of interrupt source set register. The occurrence of these interrupts are dis-

criminated by interrupt source discrimination register.
