Register R05 – Pull-downs, Pull-ups, current regulation and fault latch.
Bits D[7:6] control the fast pull down level by the number of diodes connected in series with the gate pull-down
transistor of the Quick Trip sensor. Bits D[5:4] control the GATEA/GATEB Pull-up Current. Bit D[3] controls the
Current Regulation. Bit D[2] controls the Fault Latches Off versus Duty Cycle. Bits D[1:0] control the Drain Sense
Glitch Filter.
