another strange error in Mega128's datasheet
I use Timer1 in Fast PWM mode 15, and COM1C1:0 = 2 and I found that the actually output waveform was the opposite, so Figure 52 is fucking wrong then!!!! How could ATMEL got such...

asking for the fastest way to toggle one bit in a register
Hi, I use Mega128L and I want to toggle COM1C0 in TCCR1A, and I wrote: if ((TCCR1A & _BV(COM1C0)) == 0x00) { TCCR1A |= _BV(COM1C0); } else { TCCR1A &= ~(_BV(COM1C0)); }...
