Timing of Disabling of ITU Output by External Trigger: If the XTGD bit is cleared to 0 in
TOCR in reset-synchronized PWM mode or complementary PWM mode, when an input capture
A signal occurs in channel 1, the master enable bits are cleared to 0 in TOER, disabling ITU
output. Figure 8-55 shows the timing.
Timing of Output Inversion by TOCR: The output levels in reset-synchronized PWM mode and
complementary PWM mode can be inverted by inverting the output level select bits (OLS4 and
OLS3) in TOCR. Figure 8-56 shows the timing.
