Both the program and data memory arrays can be programmed using the SPI bus while
RESET is pulled to GND. The serial interface consists of pins SCK, MOSI (input) and
MISO (output), see Figure 29. After RESET is set low, the Programming Enable instruc-
tion needs to be executed first before program/erase instructions can be executed.
