Timer 2 Output Mode 7

In this mode the timer overflow defines the period and the compare register defines the

duty cycle. During one period only the first compare match occurrence is used to toggle

the timer output flip-flop, until the overflow all further compare match are ignored. This

avoids the situation that changing the compare register causes the occurrence of sev-

eral compare match during one period. The resolution at the pulse-width modulation

Timer 2 mode 1 is 12-bit and all other Timer 2 modes are 8-bit.
