Section 8 EXDMA Controller
8.3
The EXDMAC has the following registers.
8.3.1
EDSAR is a 32-bit readable/writable register that specifies the transfer source address. An address
update function is provided that updates the register contents to the next transfer source address
each time transfer processing is performed. In single address mode, the EDSAR value is ignored
when a device with DACK is specified as the transfer source. The upper 8 bits of EDSAR are
reserved; they are always read as 0 and cannot be modified.
EDSAR can be read at all times by the CPU. When reading EDSAR for a channel on which
EXDMA transfer processing is in progress, a longword-size read must be executed. Do not write
to EDSAR for a channel on which EXDMA transfer is in progress. The initial values of EDSAR
are undefined.
