or via USB.
Regardless of the downloading method used, the boot program downloads a user program
into the internal RAM and then branches to the internal RAM. Figure 3.4.3 shows how the
boot program uses the internal RAM (common to all the downloading methods).
Outline of Boot Operation
The method for downloading a user program can be selected from two types: from UART,
After reset, the boot program on the internal boot ROM executes as shown in Figure 3.4.2.
