Section 10 16-Bit Integrated Timer Pulse Unit (ITU)
Bits 7 and 6—Reserved: Bit 7 is read as undefined. Bit 6 is always read as 1. The write value to
bit 7 should be 0 or 1. The write value to bit 6 should always be 1.
Bits 5 and 4—Combination Mode 1 and 0 (CMD1 and CMD0): CMD1 and CMD0 select
complementary PWM mode or reset-synchronized mode for channels 3 and 4. Set the
complementary PWM/reset-synchronized PWM mode while the timer counter (TCNT) being used
is off. When these bits are used to set complementary PWM/reset-synchronized PWM mode, they
take priority over the PWM4 and PWM3 bits in TMDR. While the complementary PWM/reset-
synchronized PWM mode settings and the SYNC4 and SYNC3 bit settings of the timer synchro
register (TSNC) are valid simultaneously, when complementary PWM mode is set, channels 3 and
4 should not be set to operate simultaneously (the SYNC 4 and SYNC 3 bits in TSNC should not
both be set to 1).
