11.4 Operation
11.4.1 System outline

(1) Outline of 6-phase PWM output
The 6-phase PWM output mode is used to generate a 6-phase PWM output wave, by using the timer AB1
(TAB1) and the TAB1 option (TAB1OP0) in combination.
The 6-phase PWM output mode is enabled by setting the TAB1CTL1.TAB1MD2 to TAB1CTL1.TAB1MD0 bits of
TAB1 to “111”.
One 16-bit counter and four 16-bit compare registers of TAB1 are used to generate a basic 3-phase wave.
The functions of the compare registers are as follows.
TAA4 can perform a tuning operation with TAB1 to generate a conversion trigger source for the A/D converter.
Remark
A dead-time interval is generated from the basic 3-phase wave generated by using three 10-bit dead-time
counters and one compare register to create a wave with a reverse phase to that of the basic 3-phase wave.
Then a 6-phase PWM output wave (U, U, V, V, W, and W) is generated.
The 16-bit counter for generating the basic 3-phase wave counts up or down. After the operation has been
started, this counter counts up. When its count value matches the cycle set to the TAB1CCR0 register, the
counter starts counting down. When the count value matches 0001H, the counter counts up again. This
means that a value two times higher than the value set to the TAB1CCR0 register + 1 is the carrier cycle.
10-bit dead-time counters 1 to 3, which generate the dead-time interval, count up. Therefore, the value set to
the TAB1 dead-time compare register (TAB1DTC) is used as a dead-time value as is. Because three counters
are used, dead time can be generated independently in phases U, V, and W. However, because there is only
one register that specifies a dead-time value (TAB1DTC), the same dead-time value is used in all three phases.
