10.6.11 Note on Writing in the Synchronizing Mode
After the synchronizing mode is selected, if the 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 of TFCR are set, note the following.
1. Writes to CMD1 and CMD0 should be done while TCNT3 and TCNT4 are halted.
2. Changes of setting from the reset-synchronized PWM mode to the complementary PWM mode
294 RENESAS
and vice versa are inhibited. Set the reset-synchronized PWM mode or complementary PWM
mode after first setting normal operation (clear CMD1 bit to 0).
