I'm currently designing a small board based around the ATtiny85. It doesn't do anything particularly exciting, just driving some logic level mosfets in order to sequence some power rails.
Due to the low pin count, I need to connect the mosfet gate pins to the MISO, MOSI and SCK pins.
I have a 100 ohm series resistor between the ATtiny85 pins and the mosfet gate, as well as a 100K pull down from gate to ground.
Is this going to cause any problems when I program the ATtiny85 via ISP ?
I'm just not sure if the mosfet is going to interfere with the programming signals.
