„AD converter
1) 12/8 bits resolution selectable
2) Analog input: 14 channels
3) Comparator mode
LC88F5LA4ACS
„Watchdog timer
1) Driven by the base timer + internal watchdog timer dedicated counter
2) Interrupt or reset mode selectable
„Interrupts (peripheral function)
• 38 sources (24 modules), 13 vector addresses
1) Provides three levels (low (L), high (H), and highest (X)) 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.

• 3 priority levels selectable.
• Of interrupts of the same level, the one with the smallest vector address takes precedence.
• A number enclosed in parentheses denotes the number of sources.
„Subroutine Stack: 6K-byte RAM area
• Subroutine calls that automatically save PSW, interrupt vector calls: 6 bytes
• Subroutine calls that do not automatically save 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 (built-in Rf circuit): For system clock (OSC1)
• VMRC oscillator circuit: For system clock (OSC1)
• Crystal oscillator circuit (built-in Rf circuit): For low-speed system clock (OSC0)
• SLRC oscillator circuit (internal): For system clock (In the case of exception processing)
„System clock divider function
• Can run on low current.
• 1/1 to 1/128 of the system clock frequency can be set.
