14.2 Configuration of DMA Controller
550
The DMA controller includes the following hardware.
(1) DMA SFR address register n (DSAn)
Address registers
Count register
Control registers
Address: FFFB0H (DSA0), FFFB1H (DSA1)
DSAn
This is an 8-bit register that is used to set an SFR address that is the transfer source or destination of DMA
channel n.
Set the lower 8 bits of the SFR addresses FFF00H to FFFFFH
This register is not automatically incremented but fixed to a specific value.
In the 16-bit transfer mode, the least significant bit is ignored and is treated as an even address.
DSAn can be read or written in 8-bit units. However, it cannot be written during DMA transfer.
Reset signal generation clears this register to 00H.
Note Except for address FFFFEH because the PMC register is allocated there.
