DMA Reload Destination Address Registers (RDAR)
The DMA reload destination address registers (RDAR) are 32-bit readable/writable registers.
When the reload function is enabled, the RDAR value is written to the destination address register
(DAR) at the end of the current DMA transfer. In this case, a new value for the next DMA transfer
can be preset in RDAR during the current DMA transfer. When the reload function is disabled,
RDAR is ignored.
To transfer data of 16-bit or 32-bit width, specify the address with 16-bit or 32-bit address
boundary respectively. To transfer data in units of 16 bytes, set a value at a 16-byte boundary.
RDAR is initialized to H'00000000 by a reset and retains the value in software standby mode and
module standby mode.
