17.5 Example of Setting of DMA Controller
17.5.1 CSI consecutive transmission
A flowchart showing an example of setting for CSI consecutive transmission is shown below.
● Consecutive transmission of CSI20 (256 bytes)
● DMA channel 0 is used for DMA transfer.
● DMA start source: INTCSI20 (software trigger (STG0) only for the first start source)
● Interrupt of CSI20 is specified by IFC03 to IFC00 = 1010B.
● Transfers FFB00H to FFBFFH (256 bytes) of RAM to FFF48H of the data register (SIO20) of CSI.
Remark IFC03 to IFC00: Bits 3 to 0 of DMA mode control registers 0 (DMC0)
