pwm_scramble
PWM scramble select. Controls mapping of PWM and NDRIVE
signals to pins OUT1 through OUT12. See Table 3 herein for
details.
dual
PWM/NDRIVE select.
0 = Only PWM outputs active for use with single input drivers
1 = PWM & NDRIVE outputs active for use with dual input
drivers
fault1_mask[17:0]
fault2_mask[17:0]
Fault1 pin output masks. Inputs are enabled for reporting when
set to logic 1. If multiple inputs are selected, output is “OR” of
selected input signals.
17 = NVM fault
16 = Internal bus fault
15 = IUVP
14 = OUVP
13 = OOVP
12 = thermistor temp alert
11 = thermistor temp shutdown
10 = PTAT temp alert
9 = PTAT temp shutdown
8 = channel 1 high side short
7 = channel 2 high side short
6 = channel 3 high side short
5 = channel 4 high side short
4 = channel 5 high side short
3 = channel 6 high side short
2 = unused
1 = MHz controller fault
0 = Calibration fault
shutdown_mask[15:0]
Shutdown control mask. Inputs are enabled for shutdown when
set to logic 1. If multiple inputs are selected, output is “OR” of
selected input signals.
15 = IUVP
14 = OUVP
13 = OOVP
12 = Individual phase current fault during active regulation
11 = thermistor temp shutdown
10 = Individual phase current fault during soft-start
9 = PTAT temp shutdown
8 = channel 1 high side short
7 = channel 2 high side short
6 = channel 3 high side short
5 = channel 4 high side short
4 = channel 5 high side short
3 = channel 6 high side short
2 = Total current fault during active regulation
1 = Total current fault during soft-start
0 = Calibration fault
ch_mask[6:1]
Channel mask. Selects number of active phases. Phases must
be selected in sequential order.
000011 = 2-phase operation
000111 = 3-phase operation
001111 = 4-phase operation
011111 = 5-phase operation
111111 = 6-phase operation
