„AD Converter : 8-bits × 11-channels
LC87F5864B
„PWM : Multifrequency 12-bit PWM × 2-channels
„Remote Control Receiver Circuit (sharing pins with P73, INT3, and T0IN)
• Noise rejection function (noise filter time constant selectable from 1 tCYC, 32 tCYC, and 128 tCYC)
„Watchdog Timer
• External RC watchdog timer
• Interrupt and reset signals selectable
„Clock Output Function
1) Able to output selected oscillation clock 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64 as system clock.
2) Able to output oscillation clock of sub clock.
„Interrupts
• 23 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.
