(Generates DMA software request) by writing any data
Note: This register can be accessed in either bytes or halfwords.
The DMA Software Request Generation Register is used to generate DMA transfer requests in
software. A DMA transfer request can be generated by writing any data to this register when
"Software start" has been selected for the cause of DMA request.
DM0SRI - DM9SRI (DMA software request generate) bit
A software DMA transfer request is generated by writing any data to this register in halfword (16
bits) or in byte (8 bits) beginning with an even or odd address when "Software" is selected as the
cause of DMA transfer request (by setting the DMA Channel Control Register D2, D3 bits to "00").
