Timer A ApplicationsMitsubishi microcomputers<strong>M16C</strong> / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER3.3 Delayed One-Shot OutputOverviewThe following are steps of outputting a pulse only once after a specified elapse since an externaltrigger is input. Figure 3.3.1 shows the operation timing, Figure 3.3.2 shows the connection diagram,and Figures 3.3.3 and 3.3.4 show the set-up procedure.Use the following peripheral function:• One-shot timer mode of timer ASpecifications(1) Set timer A0 in one-shot timer mode, and set timer A1 in one-shot timer mode with pulseoutputfunction.(2) Set 1 ms, an interval before a pulse is output, in timer A0; and set 50 µs, a pulse width, in timerA1. Both timer A0 and timer A1 use f1 for the count source.(3) Connect a 16-MHz oscillator to XIN.Operation(1) Setting the trigger select bit to “1” and setting the count start flag to “1” enables the counter oftimer A0 to count.(2) If an effective edge, selected by use of the external trigger select bit, is input to the TA0IN pin,the counter begins a down count. The counter of timer A0 performs a down count on countsource f1.(3) As soon as the counter of timer A0 becomes “000016”, the counter reloads the content of thereload register and stops counting. At this time, the timer A0 interrupt request bit gose to “1”.(4) An underflow in timer A0 triggers the counter of timer A1 and causes it to begin counting.When timer A1 begins counting, the output level of the TA1OUT pin gose to “H”.(5) As soon as the counter of timer A1 becomes “000016”, the output level of the TA1OUT pingose to “L”, the counter reloads the content of the reload register, and stops counting. At thistime, timer A1 interrupt request bit gose to “1”.464
