„AD Converter: 12 bits × 12 channels
LC87F1L16A
„PWM: Multifrequency 12-bit PWM × 2 channels
„USB Interface (host control function) × 2 channels
1) Compliant with full-speed (12M bps) specifications
2) Supports 4 transfer types (control transfer, bulk transfer, interrupt transfer, and isochronous transfer).
„Watchdog Timer
• Watchdog timer using external RC circuitry
• Interrupt and reset signals selectable
„Clock Output Function
1) Can output a clock with a clock rate of 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64 of the source oscillator clock selected
as the system clock.
2) Can output the source oscillation clock for the subclock.
„Interrupts
• 39 sources, 10 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.
No.
