Section 12 Data Transfer Controller (DTC)
[Legend]
x: Don't care
12.2.3
SAR is a 32-bit register that designates the source address of data to be transferred by the DTC.
In full address mode, 32 bits of SAR are valid. In short address mode, the lower 24 bits of SAR is
valid and bits 31 to 24 are ignored. At this time, the upper eight bits are filled with the value of
bit 23.
If a word or longword access is performed while an odd address is specified in SAR or if a
longword access is performed while address 4n + 2 is specified in SAR, the bus cycle is divided
into multiple cycles to transfer data. For details, see section 12.5.1, Bus Cycle Division.
SAR cannot be accessed directly from the CPU.
