In the 2 byte transfer mode, data are transferred as follows:
(Destination address)
(Destination address + 1)
←
(Source address)
←
(Source address + 1)
Similar data transfers are made in the modes that
“decrement the source address”, but the updated address
are different as shown in the Table 3.3 (2).
Address increment/decrement modes are applied to
memory address space and fixed addressing modes are
applied to the I/O address space. Beacause of that, the micro
DMA was designed for both I/O to memory transfers and
memory to I/O transfers.
Figure 3.3 (5) shows an example of the micro DMA
processing that handles data receiving of internal serial I/O.
This is an example of executing “an interrupt processing
program after serial data receiving” after receiving 7-frame
data (assuming 1 frame = 1 byte for this example) and saving
them into the memory addresses from FF00H to FF06H.
