18.11.32 TCCR4B – Timer/Counter4 Control Register B
288
ATmega128RFA1
• Bit 7 – ICNC4 - Input Capture 4 Noise Canceller
Timer/Counter4 has only limited functionality. It is not connected to any Input Capture
Pin. Therefore this bit has no meaningful function.
• Bit 6 – ICES4 - Input Capture 4 Edge Select
Timer/Counter4 has only limited functionality. It is not connected to any Input Capture
Pin. Therefore this bit has no meaningful function.
• Bit 5 – Res - Reserved Bit
This bit is reserved for future use. A read access always will return zero. A write access
does not modify the content.
• Bit 4:3 – WGM41:40 - Waveform Generation Mode
Combined with the WGM41:0 bits found in the TCCR4A Register, these bits control the
counting sequence of the counter, the source for maximum (TOP) counter value, and
what type of waveform generation to be used. Modes of operation supported by the
Timer/Counter unit are: Normal mode (counter), Clear Timer on Compare match (CTC)
mode, and three types of Pulse Width Modulation (PWM) modes. For more information
on the different modes see section "Modes of Operation". Note that Timer/Counter4 has
only limited functionality. It cannot be connected to any I/O pin.
