18.6 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 18-1.

Figure 18-1. Serial Programming and Verify

Note:

If the device is clocked by the internal Oscillator, there is no need to connect a clock source to the

CLKI pin.
