DMA(1,2)CNT_H [d07] Destination Address Control Flag
Control of the destination address is specified after each DMA transfer.
A setting of 00 causes an increment.
A setting of 01 causes a decrement.
A setting of 10 causes it to be fixed.
A setting of 11 causes an increment to be carried out and then a reload (returned to setting at start of
transfer) is performed after every transfer is completed.
However, when in direct sound FIFO transfer mode, the destination address is fixed and unrelated to
the setting.

DMA 3 provides memory access between the Game Pak bus and internal memory of the main unit, or
between different areas of internal memory of the main unit.
12.3.1 Source Address
Specifies the source address using 28 bits.
The area 00000000h-0FFFFFFFh (internal memory of main unit and Game Pak memory area) can be
specified.
