CTRLC - Control Register C
• Bit 3 – Reserved
This bit is unused and reserved for future use. For compatibility with future devices, always write
this bit to zero when this register is written.
• Bit 2:0 – WGMODE[2:0]: Waveform Generation Mode
These bits select the Waveform Generation Mode, and control the counting sequence of the
Counter, the TOP value, the UPDATE condition, the Interrupt/event condition, and type of wave-
form that is generated, according to
No waveform generation is performed in normal mode of operation. For all other modes the
result from the waveform generator will only be directed to the port pins if the corresponding
CCxEN bit has been set to enable this. The port pin direction must be set as output.
Table 14-4.
• Bit 7:4 – Reserved
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
• Bit 3:0 – CMPx: Compare Output Value n
These bits allow direct access to the Waveform Generator's output compare value when the
Timer/Counter is set in “OFF” state. This is used to set or clear the WG output value when the
Timer/Counter is not running.
