TCCR4C – Timer/Counter4 Control Register C
Table 15-14. Division factors of the Dead Time prescaler
• Bits 3 .. 0 - CS43, CS42, CS41, CS40: Clock Select Bits 3, 2, 1, and 0
The Clock Select bits 3, 2, 1, and 0 define the prescaling source of Timer/Counter4.
Table 15-15. Timer/Counter4 Prescaler Select
The Stop condition provides a Timer Enable/Disable function.
• Bits 7,6 - COM4A1S, COM4A0S: Comparator A Output Mode, Bits 1 and 0
