Serial Programming
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 (out-
put). See
Figure 19-1. Serial Programming and Verify
Note:
After RESET is set low, the Programming Enable instruction needs to be executed first before
program/erase operations can be executed.
Table 19-10. Pin Mapping Serial Programming
Note:
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
If clocked by internal oscillator there is no need to connect a clock source to the CLKI pin.
In
pins dedicated for the internal SPI interface.
