Table 112. Parallel Programming Characteristics, V
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
Table 113 on page 268, the pin 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 pro-
gramming operation (in the serial mode ONLY) and there is no need to first execute the
