Name
Description
0 = VDH over-voltage threshold 1 (VDHOVT1) selected
1 = VDH over-voltage threshold 2 (VDHOVT2) selected
5
OUTE
Outputs enable
0 = all the gate drivers are OFF independently from OUTEx bits setting
1 = the gate drivers can be put OFF or ON according to the OUTEx bits setting
4
CP_LOW_CONFIG
CP low configuration
0 = the gate drivers come out of forced disabled mode only once the charge pump low voltage flag
CPLOW is cleared via SPI
1 = CPLOW status flag becomes a status bit (set and reset automatically) and the gate drivers come
out of forced disabled mode automatically upon recovery from the charge pump low voltage
condition
3
CPFDD
Charge pump frequency dithering
0 = charge pump dithering doesn’t enable
1 = charge pump dithering enabled
2
EN_PWM1
PWM1 enable
0 = PWM1 disabled
1 = PWM1 enabled
1
EN_PWM2
PWM2 enable
0 = PWM2 disabled
1 = PWM2 enabled
0
EN_PWM3
PWM3 enable
0 = PWM3 disabled
1 = PWM3 enabled
