Data are transferred as shown below in the 2-byte transfer
mode.
(Transfer source address)
(Transfer source address + 1)
address + 1)
(Transfer destination address)
(Transfer destination
Transfers are also performed as shown above in “decrement
transfer source address mode” but address changes are as
shown in Table 3.3.
Address incrementation and decrementation are used for
the memory area but fixed addresses are used for ordinary input/
output addresses. Because of that, micro DMA was designed
taking into consideration input/output to memory and memory
to input/output transfers.
Figure 3.3 (5) shows and example using the micro DMA
processing mode. Built-in serial input/output receive data are
processed in the example.
In the example, 7 frames (1 frame = 1 byte in this example) of
received data are stored to memory address FF00H - FF06H
and when all of the data have been received, the “receive end
processing program” is executed.
Figure 3.3 (5). Micro DMA Processing Example
“Table 3.2 Bus operations for each instruction” above
shows the bus operation for general-purpose interrupt pro-
cessing and micro DMA processing.
The execution time (when the transfer count is not 0 after
decrementation) for micro DMA processing is 46 states (9.2
microseconds at 10MHz), regardless of whether the 1-byte or
2-byte transfer mode is used.
