10.6.11 Note on Writing in Synchronizing Mode
After synchronizing mode is selected, if TCNT is written by byte access, all 16 bits of all
synchronized counters assume the same value as the counter that was addressed.
Example: Figures 10.67 and 10.68 show byte write and word write when channels 2 and 3 are
synchronized
10.6.12 Note on Setting Reset-Synchronized PWM Mode/Complementary PWM Mode
When the CMD1 and CMD0 bits in TFCR are set, note the following.
1. Writes to CMD1 and CMD0 should be carried out while TCNT3 and TCNT4 are halted.
2. Changes of setting from reset-synchronized PWM mode to complementary PWM mode and
vice versa are prohibited. Set reset-synchronized PWM mode or complementary PWM mode
after first setting normal operation (clear CMD1 bit to 0).
