   - 19-source, 10-vectored interrupts:
    1. Three level (low, high and highest) multiple interrupts are supported. During interrupt handling, an equal or lower level interrupt request is refused.
    2. If interrupt requests to two or more vector addresses occur at once, the higher level interrupt takes precedence.
        In the case of equal priority levels, the vector with the lowest address takes precedence.
     • Priority Level : X > H > L
     • For equal priority levels, vector with lowest address takes precedence.

` Oscillation circuits
   - On-chip RC oscillation circuit used for system clock
   - On-chip CF oscillation circuit used for system clock
   - On-chip Crystal oscillation circuit used for system clock and time-base clock
` Standby function
   - HALT mode
     HALT mode is used to reduce power consumption. Program execution is stopped. Peripheral circuits still operate.
     1. Oscillation circuits are not stopped automatically
     2. Release on system reset
   - HOLD mode
     HOLD mode is used to reduce the power dissipation. Both program execution and peripheral circuits are stopped.
     1. CF, RC and crystal oscillation circuits stop automatically
     2. Release occurs on any of the following conditions
         •input to the reset pin goes low
         •a specified level is input to at least one of INT0, INT1, INT2, INT4, INT5
         •an interrupt condition arises at port 0
   - X'tal HOLD mode
     X'tal HOLD mode is used to reduce power consumption. Program execution is stopped. All peripheral circuits except the base timer are stopped.
     1. CF and RC oscillation circuits stop automatically
     2. Crystal oscillator is maintained in its state at HOLD mode inception.
     3. Release occurs on any of the following conditions
         •input to the reset pin goes low
         •a specified level is input to at least one of INT0, INT1, INT2, INT4, INT5
         •an interrupt condition arises at port 0
         •an interrupt condition arises at the base-timer
