I'm doing Serial (SPI) programming of the ATtiny24A. I have an external 8 MHz oscillator for the ATtiny.
But sometimes when I flash the program memory and then read it back I get a mismatch on some byte.
Now when I check the datasheet it says on page 180 that the 1/tCLCL (Oscillator Frequency) is max 4MHz (My Vcc is 3.3V). Could it be this that causes the intermittent problem?
Can I solve it by setting the CKDIV8 fuse bit so the CPU runs at 1 MHz?
