LC88F40H0PA/H0PAU/F0PA/F0PAU/D0PA/D0PAU
■PWM: Multifrequency 12-bit PWM × 4 channels
• PWM0: Multifrequency 12-bit PWM × 2 channels (PWM0A and PWM0B)
• PWM1: Multifrequency 12-bit PWM × 2 channels (PWM1A and PWM1B)
1) 2-channel pairs controlled independently of one another
2) Clock source selectable from system clock or VCO clock
3) 8-bit prescaler: TPWMR0 = (prescaler value + 1) × clock period
4) 8-bit fundamental wave PWM generator circuit + 4-bit additional pulse generator circuit
5) Fundamental wave PWM mode
Fundamental wave period : 16 TPWMR0 to 256 TPWR0
High pulse width
: 0 to (Fundamental wave period - TPWMR0)
6) Fundamental wave + additional pulse mode
Fundamental wave period : 16 TPWR0 to 256 TPWR0
Overall period
: Fundamental wave period × 16
High pulse width
: 0 to (Overall period - TPWR0)
■Watchdog Timer: 1 channel
• Driven by the timer 8 + internal watchdog timer dedicated counter
• Interrupt or reset mode selectable
■Interrupts
• 63 sources, 16 vector addresses
1) Provides three levels 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.
No.

• 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: Entire maximum RAM space (The stack is allocated in RAM.)
• Subroutine calls that automatically save PSW, interrupt vector calls: 6 bytes
• Subroutine calls that do not automatically save PSW: 4 bytes
■High-speed Multiplication/division instructions
• 16 bits × 16 bits
• 16 bits ÷ 16 bits
• 32 bits ÷ 16 bits
