Both the Flash and EEPROM memory arrays can be programmed using the serial SPI bus
while RESET is pulled to GND. The serial interface consists of pins SCK, MOSI (input) and
MISO (output). After RESET is set low, the Programming Enable instruction needs to be exe-
cuted first before program/erase operations can be executed.
