Transfer Source/Transfer Destination Address Setting Registers (Dmasa0 To Dmasa4/Dmada0 To Dmada4) - Fujitsu FR60 Hardware Manual

CHAPTER 14 DMA CONTROLLER (DMAC)
14.2.3 Transfer Source/Transfer Destination Address Setting
Registers (DMASA0 to DMASA4/DMADA0 to DMADA4)
The transfer source/transfer destination address setting registers (DMASA0 to
DMASA4/DMADA0 to DMADA4) control the operation of the DMAC channels. There is a
separate register for each channel.
This section describes the configuration and functions of the transfer source/transfer
destination address setting registers (DMASA0 to DMASA4/DMADA0 to DMADA4).
■ Bit Configuration of Transfer Source/Transfer Destination Address Setting Registers
(DMASA0 to DMASA4/DMADA0 to DMADA4)
The transfer source/transfer destination address setting registers (DMASA0 to DMASA4/
DMADA0 to DMADA4) are a group of registers that store the transfer source/transfer destination
addresses. Each register is 32-bit length.
Figure 14.2-4 shows the bit configuration of the transfer source/transfer destination address
setting registers (DMASA0 to DMASA4/DMADA0 to DMADA4).
