No value other than “0” can be written.
Selecting three-phase PWM output mode causes the dead time timer, the U, V, W phase output control circuits, and the
timer B2 interrupt occurrences frequency set circuit works.
For U, U, V, V, W and W output from P8
required.
In triangular wave modulation mode: The dead time timer starts in synchronization with the falling edge of timer Ai
output. The data transfer from the three-phase buffer register to the three-phase output shift register is made only once in
synchronization with the transfer trigger signal after writing to the three-phase output buffer register.
In sawtooth wave modulation mode: The dead time timer starts in synchronization with the falling edge of timer A
output and with the transfer trigger signal. The data transfer from the three-phase output buffer register to the three-
phase output shift register is made with respect to every transfer trigger.
Set bit 1 of this register to "1" after setting timer B2 interrupt frequency set counter.
Rewrite the INV00 to INV02 and INV06 bits when the timers A1,A2,A4 and B stop.
