14.3.3
DMA Destination Address Registers 0 to 11 (DAR0 to DAR11)
DAR are 32-bit readable/writable registers that specify the destination address of a DMA transfer.
During a DMA transfer, these registers indicate the destination address of the next transfer.
A word or longword boundary address should be specified when a word or longword transfer is
performed respectively. A 16-byte or 32-byte boundary value should be specified when a 16-byte
or 32-byte transfer is performed respectively.
In 29-bit address mode, the source address is changed as follows before it is output.
•
The upper three bits are output as 000 when bits 31 to 29 are not 111 and areas 0 to 6 are used.
•
The upper three bits are output as 111 when bits 31 to 29 are not 111 and area 7 is used.
•
The written address is output as it is when bits 31 to 29 are 111.
In 32-bit address mode, the written address is output as it is.
The initial value of DAR is undefined.
