Serial Programming
ATtiny261A/461A/861A
Table 18-7.
Table 18-8.
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. Serial Programming and Verify
