Triangular Wave Modulation
To generate a PWM waveform of triangular wave modulation, set "0" in the modulation mode select bit (bit
6 at address 01C816). Also, set "1" in the timers A4-1, A1-1, A2-1 control bit (bit 1 at address 01C916). In
this mode, each of timers A4, A1, and A2 has two timer registers, and alternately reloads the timer register's
content to the counter every time timer B2 counter's content becomes 000016. If "0" is set to the effective
interrupt output specification bit (bit 1 at address 01C816), the frequency of interrupt requests that occur
every time the timer B2 counter's value becomes 000016 can be set by use of the timer B2 counter (address
01CD16) for setting the frequency of interrupt occurrences. The frequency of occurrences is given by a set
value (
≠ 0).
Setting "1" in the effective interrupt output specification bit (bit 1 at address 01C816) provides the means to
choose which value of the timer A1 reload control signal to use, "0" or "1", to cause timer B2's interrupt
request to occur. To make this selection, use the effective interrupt output polarity selection bit (bit 0 at
address 01C816).
An example of U phase waveform is shown in Figure 1.15.6, and the description of waveform output work-
ings is given below. Set "1" in DU0 bit (bit 0 at address 01CA16). And set "0" in DUB0 bit (bit 1 at address
01CA16). In addition, set "0" in DU1 bit (bit 0 at address 01CB16) and set "1" in DUB1 bit (bit 1 at address
01CB16). Also, set "0" in the effective interrupt output specification bit (bit 1 at address 01C816) to set a
value in the timer B2 interrupt occurence frequency set counter. By this setting, a timer B2 interrupt occurs
when the timer B2 counter's content becomes 000016 as many as (setting) times. Furthermore, set "1" in
the effective interrupt output specification bit (bit 1 at address 01C816), set "0" in the effective interrupt
output polarity select bit (bit 0 at address 01C816) and set "1" in the interrupt occurence frequency set
counter (address 01CD16). These settings cause a timer B2 interrupt to occur every other interval when the
U phase output goes to "H".
When the timer B2 counter's content becomes 000016, timer A4 starts outputting one-shot pulses. In this
instance, the content of DU1 bit (bit 0 at address 01CB16) and that of DU0 bit (bit 0 at address 01CA16) are
set in the three-phase output shift register (U phase), the content of DUB1 bit (bit 1 at address 01CB16) and
__
that of DUB0 bit (bit 1 at address 01CA16) are set in the three-phase output shift register (U phase). After
triangular wave modulation mode is selected, however, no setting is made in the shift register even though
the timer B2 counter's content becomes 000016.
__
The value of DU0 bit and that of DUB0 bit are output to the U terminal (P80) and to the U terminal (P81)
respectively. When the timer A4 counter counts the value written to timer A4 (addresses 038F16 and
038E16) and when timer A4 finishes outputting one-shot pulses, the three-phase shift register's content is
shifted one position, and the value of DU1 bit and that of DUB1 bit are output to the U phase output signal
__
and to U phase output signal respectively. At the this time, one-shot pulses are output from the timer for
setting dead time used for setting the time over which the "L" level of the U phase waveform doesn't lap over
__
the "L" level of the U phase waveform, which has the opposite phase of the former. The U phase waveform
output that started from the "H" level keeps its level until the timer for setting dead time finishes outputting
one-shot pulses even though the three-phase output shift register's content changes from "1" to "0" by the
effect of the one-shot pulses. When the timer for setting dead time finishes outputting one-shot pulses, "0"
already shifted in the three-phase shift register goes effective, and the U phase waveform changes to the
"L" level. When the timer B2 counter's content becomes 000016, the timer A4 counter starts counting the
value written to timer A4-1 (addresses 01C116 and 01C016), and starts outputting one-shot pulses. When
timer A4 finishes outputting one-shot pulses, the three-phase shift register's content is shifted one position,
but if the three-phase output shift register's content changes from "0" to "1" as a result of the shift, the output
level changes from "L" to "H" without waiting for the timer for setting dead time to finish outputting one-shot
