Figure 3.3 (4). Parameters for Micro DMA Processing
The parameters for the micro DMA processing are located
in the internal RAM area (See Table 3.3 (1) Interrupt Sources).
The start address of each parameter is “FF00H + interrupt
vector value”, from which a six bytes’ space is used for the
parameter. This space can be used for any other memory
purposes if the micro DMA processing is not used.
The parameters normally consist of the number of trans-
fer, addresses of destination and source, and transfer mode.
The number of transfer indicates the number of data transfer
accepted in the micro DMA processing.
The amount of data transferred by a single micro DMA
processing is 1 or 2 bytes. The number of transfers is 256
when the number of transfers value is “00H”. Both the destination
and source addresses are specified by 2 byte data. The
address space available for the micro DMA processing ranges
from 0000H to FFFFH.
Bits 0 and 1 of the transfer mode indicates the mode
updating the source and/or destination, and the bit 2 indicates
the data length (1 byte or 2 bytes).
Table 3.3 (2) shows the relation between the transfer
mode and the result of updating the destination/source
addresses.
