9.1.20 ALARM_EN
The ALARM_EN register allows the selection of which alarm signals are used to generate
the FLAG
output. If the respective bit of the ALARM_EN register is set high, the alarm
condition forces the FLAG
pin output down.
9.1.21 GATECFG1
The GATECFG1 register has the following structure:
The IGATE parameter selects the sink/source current used by gate driving circuitry to
charge/discharge the respective gate during commutations. Seven possible values ranging
from 4 mA to 96 mA are available, as shown in Table 25.
