Various write, read, and erase operations are needed for a proper download environment. functions of the bootstrap loader: Definition of read: Apply data to pin P1.0/TA0 (BSLTX) and transmit peripheral registers or memory data to pin P1.0/TA0. write: Read data from pin P1.1/TA0/MCLK (BSLRX) and write it to flash memory. |
