OCD_TH
The OCD_TH register contains the overcurrent threshold value (see paragraph
details). The available range is from 375 mA to 6 A, steps of 375 mA as shown in
Table 14.
STALL_TH
The STALL_TH register contains the stall detection threshold value (see paragraph
details). The available range is from 31.25 mA to 4 A with a resolution of 31.25 mA.
Table 15.
STEP_MODE
The STEP_MODE register has the following structure:
Table 16.
The STEP_SEL parameter selects one of eight possible stepping modes:
