90 / 315 page  Under development Preliminary Specifications REV.B Specifications in this manual are tentative and subject to change. Mitsubishi microcomputers M16C/80 (144-pin version) group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Timer A 90 Timer A Figure 1.13.1 shows the block diagram of timer A. Figures 1.13.2 to 1.13.4 show the timer A-related registers. Except in event counter mode, timers A0 through A4 all have the same function. Use the timer Ai mode register (i = 0 to 4) bits 0 and 1 to choose the desired mode. Timer A has the four operation modes listed as follows: • Timer mode: The timer counts an internal count source. • Event counter mode: The timer counts pulses from an external source or a timer over flow. • One-shot timer mode: The timer stops counting when the count reaches “0000 16”. • Pulse width modulation (PWM) mode: The timer outputs pulses of a given width.
