Table 29-14. Parallel Programming Characteristics, V
Notes:
Both the Flash and EEPROM memory arrays can be programmed using a serial programming
bus while RESET is pulled to GND. The serial programming interface consists of pins SCK, PDI
(input) and PDO (output). After RESET is set low, the Programming Enable instruction needs to
be executed first before program/erase operations can be executed. NOTE, in
page
dedicated for the internal Serial Peripheral Interface - SPI.
