15.5.1 CSI consecutive transmission
A flowchart showing an example of setting for CSI consecutive transmission is shown below.
• Consecutive transmission of CSI10 (256 bytes)
• DMA channel 0 is used for DMA transfer.
• DMA start source: INTCSI10 (software trigger (STG0) only for the first start source)
• Interrupt of CSI10 is specified by IFC03 to IFC00 = 1000B.
• Transfers FFB00H to FFBFFH (256 bytes) of RAM to FFF44H of the data register (SIO10) of CSI.
Remark IFC03 to IFC00: Bits 3 to 0 of DMA mode control registers 0 (DMC0)
