ATmega128RFA1
COM4A1:0 bit functionality when the WGM43:0 bits are set to a normal or a CTC mode
(non-PWM). For the other functionality refer to section "Modes of Operation".
Table 18-18 COM4A Register Bits
• Bit 5:4 – COM4B1:0 - Compare Output Mode for Channel B
The Timer/Counter4 has only limited functionality. Therefore the COM4B1:0 bits do not
control the output compare behavior of any pin. The following table shows the
COM4B1:0 bit functionality when the WGM43:0 bits are set to a normal or a CTC mode
(non-PWM). For the other functionality refer to section "Modes of Operation".
Table 18-19 COM4B Register Bits
• Bit 3:2 – COM4C1:0 - Compare Output Mode for Channel C
The Timer/Counter4 has only limited functionality. Therefore the COM4C1:0 bits do not
control the output compare behavior of any pin. The following table shows the
COM4C1:0 bit functionality when the WGM43:0 bits are set to a normal or a CTC mode
(non-PWM). For the other functionality refer to section "Modes of Operation".
Table 18-20 COM4C Register Bits
• Bit 1:0 – WGM41:40 - Waveform Generation Mode
Combined with the WGM43:2 bits found in the TCCR4B 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.
