This is the process they are following; however, this partisan approach completely cuts-out the rights of the minority (republicans) and the impeachment due process rights of the executive. In addition to being non-volatile, flash memory offers fast read access times, although not as fast as static RAM or ROM. The examples provided from SiLabs are currently rare and IMHO not very well documented. The only purpose of this program is to turn on a few LED diodes on port B. bin In any case it erases the flash and then disconnects. The code sample should illustrate how the connections work.
