ATmega164P/324P/644P
Table 13-7 on page 105 shows the COM0B1:0 bit functionality when the WGM02:0 bits are set
to phase correct PWM mode.
Note:
1. A special case occurs when OCR0B equals TOP and COM0B1 is set. In this case, the Com-
pare Match is ignored, but the set or clear is done at TOP. See “Phase Correct PWM Mode” on
page 100 for more details.
• Bits 3:2 – Res: Reserved Bits
These bits are reserved bits in the ATmega164P/324P/644P and will always read as zero.
• Bits 1:0 – WGM01:0: Waveform Generation Mode
Combined with the WGM02 bit found in the TCCR0B Register, these bits control the counting
sequence of the counter, the source for maximum (TOP) counter value, and what type of wave-
form generation to be used, see Table 13-8 on page 105. Modes of operation supported by the
Timer/Counter unit are: Normal mode (counter), Clear Timer on Compare Match (CTC) mode,
and two types of Pulse Width Modulation (PWM) modes (see “Modes of Operation” on page
122).
Notes:
1. MAX
= 0xFF
2. BOTTOM = 0x00
