Address: FFFBAH (DMC0), FFFBBH (DMC1)
Symbol
DMCn
(1) DMA mode control register n (DMCn)
The DMCn register is a register that is used to set a transfer mode of DMA channel n. It is used to select a
transfer direction, data size, setting of pending, and start source. Bit 7 (STGn) is a software trigger that starts
DMA.
Rewriting bits 6, 5, and 3 to 0 of the DMCn register is prohibited during operation (when DSTn = 1).
The DMCn register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Notes 1. The software trigger (STGn) can be used regardless of the IFCn0 to IFCn3 bits values.
Remark
DMA transfer is performed once by writing 1 to the STGn bit when DMA operation is enabled (DENn = 1).
When this bit is read, 0 is always read.
DWAITn
DMA transfer that has been held pending can be started by clearing the value of the DWAITn bit to 0.
It takes 2 clocks to actually hold DMA transfer pending when the value of the DWAITn bit is set to 1.
STGn
2. When DMA transfer is held pending while using both DMA channels, be sure to hold the DMA transfer
