chth
Description:
Changes the thresholds for the selected V
DS
and V
SRC
feedback comparator.
These are the same values as in registers Vds_threshold_hs_partx (16Bh, 16Ch),
Vsrc_threshold_hs_partx (16Dh, 16Eh) and Vds_threshold_ls_partx (16Fh, 170h).
This operation is successful only if the microcore has the right to drive the output related
to selected threshold. The configuration of the high-side predriver V
SRC
threshold is also
impacted by the bootstrap initialization mode.
Assembler syntax:
chth SelFbk ThLevel;
Operands:
•
SelFbk – Operand defines the threshold comparator to be selected
•
ThLevel – This operand specifies one of the 16 threshold level values
