• 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):
• CF oscillator circuit:
• RC oscillator circuit (external RCR1):
• Crystal oscillator circuit (Rf built-in):
• RC oscillator circuit (external RCR0):
• SLRC oscillator circuit (internal):
For system clock
For system clock (OSC1)
For system clock (OSC1)
For low-speed system clock (OSC0) (option available)
For low-speed system clock (OSC0)
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 .
