In the 6-phase PWM output mode, compare registers 1 to 3 (TAB1CCR1, TAB1CCR2, and TAB1CCR3) are used to
set the duty factor, and compare register 0 (TAB1CCR0) is used to set the cycle. By setting these four registers
and by starting the operation of TAB1, three types of PWM output waves (basic 3-phase waves) with a variable duty
factor are generated. These three PWM output waves are input to the timer Q option unit (TMQOP) and their
inverted signal with dead-time is created to generate three sets of (six) PWM waves.
The TMQOP unit consists of three 10-bit counters (dead-time counters 1 to 3) that operate in synchronization with
the count clock of TAB1, and a TAB1 dead-time compare register (TAB1DTC) that specifies dead time. If “a” is set
to the TAB1DTC register, the dead-time value is “a”, and interval “a” is created between a positive-phase wave and
a negative-phase wave.
