Good news everyone,
Today I encountered a problem with attiny84A - there is no clock input (SCK) on the chip to connect it to USBASP.
The pin description in datasheet does not mention SCK, as well as Timing and Control unit is not directly connected to any pin.
USBAsp interface provides VCC, GND, RST, MISO, MOSI, and SCK to connect to the chip.
I use ATTiny84A-PU, 14 pin. The datasheet for your convenience: http://www.atmel.com/images/doc8006.pdf
How do I connect ATTiny84A with USBASP to burn a program?
Appreciate any suggestions.
