7. DMA Controller
7.2.1
A memory address register (MAR) is a 32-bit readable/writable register that specifies a source or
destination address. The transfer direction is determined automatically from the activation source.
An MAR consists of four 8-bit registers designated MARR, MARE, MARH, and MARL. All bits
of MARR are reserved; they cannot be modified and are always read as 1.
An MAR functions as a source or destination address register depending on how the DMAC is
activated: as a destination address register if activation is by a receive-data-full interrupt from the
serial communication interface (SCI) (channel 0) or by a conversion-end interrupt from the A/D
converter, and as a source address register otherwise.
The MAR value is incremented or decremented each time one byte or word is transferred,
automatically updating the source or destination memory address. For details, see section 7.3.4,
Data Transfer Control Registers (DTCR).
The MARs are not initialized by a reset or in standby mode.
7.2.2
An I/O address register (IOAR) is an 8-bit readable/writable register that specifies a source or
destination address. The IOAR value is the lower 8 bits of the address. The upper 16 address bits
are all 1 (H'FFFF).
