ATmega164A/PA/324A/PA/644A/PA/1284/P
Table 15-7 on page 106 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 101 for more details.
Bits 3:2 – Reserved
These bits are reserved bits in the Atmel
ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P 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 15-8 on page 106. 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
Notes:
1. MAX
= 0xFF
2. BOTTOM = 0x00
