OCD_TH
The OCD_TH register contains the overcurrent threshold value (Section 6.9 for details). The
available range is from 31.25 mV to 1 V, steps of 31.25 mV, as shown in Table 18.
9.1.18
STALL_TH
The STALL_TH register contains the stall detection threshold value. The available range is
from 31.25 mV to 1 V with a resolution of 31.25 mV.
