Notes:
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 executed first
before program/erase operations can be executed. NOTE, in
mapping for SPI programming is listed. Not all parts use the SPI pins dedicated for the internal
SPI interface.

Notes:
When programming the EEPROM, an auto-erase cycle is built into the self-timed programming
operation (in the serial mode ONLY) and there is no need to first execute the Chip Erase instruc-
