counter is incremented by “1” each time the timer B2 underflows, regardless of whether the INV00 and INV01 bits are
set. When setting the INV01 bit to "1", the first interrupt is generated when the timer B2 underflows n-1 times, if n is
the value set in the ICTB2 counter. Subsequent interrupts are generated every n times the timer B2 underflow.
other output functions, enter a high-impedance state. When INV03 is set to "1", U/V/W corresponding pins generate
the three-phase PWM output.
• When reset
• When positive and negative go active (INV05="1") simultaneously while INV04 bit is “1”
• When set to “0” by program
• When input on the SD pin changes state from “H” to “L” regardless of the value of the INVCR1 bit. (The INV03 bit
cannot be set to “1” when SD input is “L”.)
INV03 is set to "0" when both INV04 bit and INV05 bit are set to "1".

Setting this bit to “1” generates a transfer
trigger. If the INV06 bit is “1”, a trigger for
the dead time timer is also generated.
