| pSrc | Pointer to transfer origin |
| offset | Offset |
| szByte | Transfer size (in bytes) |
None.
This function uses DMA to transfer OAM data to the sub 2D Engine OAM. An offset can be specified for the transfer destination address. The DMA channel that is used is GX_DMAID (defined in gxcommon.h). The transfer destination address is HW_DB_OAM in the ARM9 memory space + offset. Both offset and szByte must be multiples of 4.
Notes: Because the DMA transfer is carried out internally, the transfer source data must be written to main memory in advance using a function such as DC_FlushRange.
If the regions for transfer source and transfer destination overlap, the operation result is not guaranteed.
