parameter:
4.2.3
This function disables commutation processing on one HD channel. This function has the following
parameter:
4.2.4
This function sets the Direction value. Use this function when the automatic direction detection is off
(direction_on_off=ETPU_HD_DIRECTION_AUTO_OFF), in order to select which commutation
command is used. This function has the following parameters:

channel_phaseB (uint8_t) - This is the Phase B channel number. This parameter should be
assigned a value of 0-31 for ETPU_A, and 64-95 for ETPU_B.
channel_phaseC (uint8_t) - This is the Phase C channel number. This parameter should be
assigned a value of 0-31 for ETPU_A, and 64-95 for ETPU_B.
channel_phaseD (uint8_t) - This is the Phase D channel number. This parameter should be
assigned a value of 0-31 for ETPU_A, and 64-95 for ETPU_B.
priority (uint8_t) - This is the priority to assign to the HD function. This parameter should be
assigned a value of:
— FS_ETPU_PRIORITY_HIGH
— FS_ETPU_PRIORITY_MIDDLE
— FS_ETPU_PRIORITY_LOW
channel (uint8_t) - This is the Phase A channel number. This parameter must be assigned the
same value as was assigned to the channel_phaseA parameter in the initialization routine. If there
are more HDs running simultaneously on the eTPU(s), the channel parameter distinguishes which
HD function is accessed.
channel (uint8_t) - This is the Phase A channel number. This parameter must be assigned the
same value as was assigned to the channel_phaseA parameter in the initialization routine. If there
are more HDs running simultaneously on the eTPU(s), the channel parameter distinguishes which
HD function is accessed.
channel (uint8_t) - This is the Phase A channel number. This parameter must be assigned the

HD function is accessed.
