direction (uint8_t) - This parameter should be assigned a value of:
— ETPU_HD_DIRECTION_INC
— ETPU_HD_DIRECTION_DEC
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.
value (int24_t) - This is the Revolution Counter value to be set.
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.
