3 / 21 page LC866448B/44B/40B/36B/32B/28B/24B/20B/16B/12B/08B No.6699-3/21 (8) Timer - Timer 0 16-bit timer/counter 2-bit prescaler + 8-bit programmable prescaler Mode 0 : Two 8-bit timers with programmable prescaler Mode 1 : 8-bit timer with programmable prescaler + 8-bit counter Mode 2 : 16-bit timer with programmable prescaler Mode 3 : 16-bit counter The resolution of Timer is tCYC. (tCYC: cycle time) - Timer 1 16-bit timer/PWM Mode 0 : Two 8-bit timers Mode 1 : 8-bit timer + 8-bit PWM Mode 2 : 16-bit timer Mode 3 : Variable-bit PWM (9-16 bits) In Mode 0 and Mode 1,the resolution of Timer and PWM is tCYC. In Mode 2 and Mode 3,the resolution of Timer and PWM selectable: tCYC or 1/2 tCYC by program - Base timer Every 500ms overflow system for a clock application (using 32.768kHz crystal oscillation for Base timer clock) Every 976µs, 3.9ms, 15.6ms, 62.5ms overflow system (using 32.768kHz crystal oscillation for Base timer clock) The Base timer clock selectable; 32.768kHz crystal oscillation, System clock, and programmable prescaler output of Timer 0 (9) Buzzer output - The Buzzer sound frequency selectable; 4KHz, 2KHz (using 32.768kHz crystal oscillation for Base timer clock) (10) Remote-control receiver circuit (Shares with the P73/INT3/T0IN terminal) - Noise Rejection function (the time constant of noize rejection filter: 1tCYC/16tCYC/64tCYC) (tCYC: instruction cycle time) - Switch Polarity function (11) Watchdog timer - The watchdog timer is taken on RC outside - Watchdog timer operation selectable: interrupt system, system reset (12) Interrupt system - 14-source 10-vectored interrupts : 1. External interrupt INT0 (include watchdog timer) 2. External interrupt INT1 3. External interrupt INT2, Timer/counter T0L (Lower 8-bit) 4. External interrupt INT3, Base timer 5. Timer/counter T0H (Upper 8-bit) 6. Timer T1L, Timer T1H 7. Serial-interface SIO0 8. Serial-interface SIO1 9. AD converter 10. VFD automatic display controller, Port 0 - Built-in Interrupt Priority control register Microcontroller allows 3 levels of interrupt; low level, high level, and highest level of multiplex interrupt. It can specify a low level or a high level interrupt priority from INT2/T0L through port 0 (i.e. the above interrupt number from three through ten). It can also specify a low level or the highest level interrupt priority to INT0 and INT1. |
