The VCP1 and VCP2 require setting up the following context per user channel:
Several user channels can be programmed prior to starting the VCPs. A suggested implementation is to use the EDMA interrupt generation capabilities (refer to Section 18.2.4.9 EDMA Interrupts in Section 18.2Enhanced DMA controller) and program the EDMA to generate an interrupt after the user channel's last VCPnREVT synchronized EDMA transfer has completed.
