void GX_LoadOBJExtPltt(const void *pSrc, u32 destSlotAddr, u32 szByte);
| pSrc | Pointer to transfer origin |
| destSlotAddr | Address to inside of the transfer source OBJ expanded palette slot |
| szByte | Transfer size (in bytes) |
None.
This function uses DMA to transfer OBJ palette data to the Main 2D Engine's OBJ Extended palette. The transfer destination address (in the OBJ Extended palette) can be specified. Use the GX_DMAID DMA channel (defined in gxcommon.h). Both destSlotAddr and szByte must be 4-byte aligned. Call this function between the GX_BeginLoadOBJExtPltt and GX_EndLoadOBJExtPltt functions.
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 undefined. Do not call GX_SetBankForOBJExtPltt, GX_ResetBankForOBJExtPltt, or GX_DisableBankForOBJExtPltt between GX_BeginLoadOBJExtPltt and GX_EndLoadOBJExtPltt.
