(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.
