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.
