⎯ Two types of interrupt requests (generated when the byte count reaches "0")
• Interrupt request signals for each channel
• Interrupt request signal common to all channels
1. Single data transfer: Transfer in one read cycle and one write cycle by the DMAC (in
2. Single operand transfer: Continuous data transfer by the DMAC on one channel
3. One DMA transfer: Transferring a number of data, from the start address to the end
4. Channel number: n = 0 to 7
5. Request source number: k = 1 to 36, m = 0 to 36
6. BIU: Bus Interface Unit (peripheral module). One of the following four kinds according to
the case of dual address transfer)
(amount of data to be transferred is set in a register)
address set in the byte count register
the source or destination of transfer.
