5. GRA3 is the waveform period register. Set the upper limit of TCNT3–1*. Set the transition
6. Set the STR3 and STR4 bits in the TSTR to 1 to let TCNT3 and TCNT4 start counting.
Complementary PWM Mode Operation: Figure 10.34 shows an example of operation in the
complementary PWM mode. TCNT3 and TCNT4 operate as up/downcounters, counting down
from compare match of TCNT3 and GRA3 and counting up when TCNT4 underflows. PWM
waveforms are output by repeated compare matches with each of the general registers in the
266 RENESAS
Note
times of the PWM output waveforms in GRB3, GRA4, and GRB4. Set times within the
compare match range of TCNT3 and TCNT4.
Note:
T
(X: initial setting of GRB3, GRA4, and GRB4; T: initial setting of TCNT3)
To re-engage the complementary PWM mode after it has been aborted, start settings
from step 1.
