• Priority levels X > H > L

• When interrupts of the same level occur at the same time, an interrupt with a smaller vector address is given priority.

• The number in parentheses indicates the number of sources in a module.

Subroutine stack: 8K-byte RAM area

• Subroutine calls that automatically save the PSW, interrupt vector call: 6 bytes

• Subroutine calls that do not automatically save the PSW: 4 bytes

Multiplication/division instructions

• 16 bits × 16 bits

(18 tCYC execution time)

• 16 bits ÷ 16 bits

(18 to 19 tCYC execution time)

• 32 bits ÷ 16 bits

(18 to 19 tCYC execution time)

■Oscillator circuits

• RC oscillator circuit (internal):

For system clock

• CF oscillator circuit:

For system clock (OSC1)

• RC oscillator circuit (external RCR1): For system clock (OSC1)

• Crystal oscillator circuit (Rf built-in):

For low-speed system clock (OSC0) (option available)

• RC oscillator circuit (external RCR0): For low-speed system clock (OSC0)

• SLRC oscillator circuit (internal):

For system clock (used during exception processing)

■System clock frequency divider function

• Can run on low consumption current.

• Supports frequency-dividing of 1/1 to 1/128 of the system clock

Standby function

• HALT mode: Halts instruction execution while allowing the peripheral circuits to continue operation.

1) Oscillation is not halted automatically.

2) HALT mode is released by a system reset or an interrupt .
