INV13 (Carrier wave rise/fall detect flag) (b3)
The INV13 bit is enabled only when the INV06 bit is set to 0 (triangular wave modulation mode) and the
INV11 bit to 1 (three-phase mode 1).
INV16 (Dead time timer trigger select bit) (b6)
If both of the following conditions are met, set the INV16 bit to 1 (rising edge of the three-phase output
shift register output).
•
The INV15 bit is 0 (dead time timer enabled)
•
Bits Dij and DiBj always have different values when the INV03 bit is set to 1 (three-phase control
timer output enabled). The high- and low-side signals always output opposite level signals at any
time except dead time. (i = U, V, or W; j = 0, 1).
If either of the above conditions is not met, set the INV16 bit to 0 (dead time timer is triggered on the
falling edge of a one-shot pulse of timers).
