Figure 3.3 (4). Micro DMA Processing Parameters
The parameters used for the micro DMA processing are
located in the external RAM area (See Table 3.3 (1) Interrupt
sources). The start address of each micro DMA processing
parameter is [FF00H + interrupt vector value], 6 bytes of which
are used for the parameters. When the micro DMA processing
mode is not used, this area can be used as user memory.
The parameters include transfer count, transfer destination
address, transfer source address and transfer mode. Transfer
count specifies the number of times data will be transferred by
micro DMA processing. Either 1 or 2- bytes of data are trans-
ferred at one time by micro DMA processing. Data are
transferred 256 times with a transfer count of “00H”.
The addresses 0000H - FFFFH are used in micro DMA
processing (at not use MMU function). Bits 0 and 1 specify the
transfer destination or transfer source address change mode.
Bit 2 specifies the length (1 or 2 bytes) of the data handled.
Table 3.3 (2) shows the relationship between the transfer
mode and transfer destination/transfer source address incre-
ment/decrement values.
