In the datasheet, they say "the MCP is able to stream output data continuously with no additional command if the communication is not stopped with a CS rising edge". An image illustrating the...

Hey, I want to use the uart0 for both communication with usb and also for flashing ( while in serial bootloader mode) the new firmware.
