6.6.1 General
The counter/timer has two basic modes of operation: it can count internal or external
events, or it can count an internal clock source while an external input signal is asserted,
thus timing the width of the external input signal.

• The counter can count the rising, falling, or both edges of the selected input pin.
• The counter can decode and count quadrature encoded input signals.

This read-only bitfield is reserved and always has the value zero.
Timer Channel Enable
These bits enable the prescaler (if it is being used) and counter in each channel. Multiple ENBL bits can
be set at the same time to synchronize the start of separate counters. If an ENBL bit is set, then the
corresponding channel starts its counter as soon as the CTRL[CM] field has a value other than 0. When
an ENBL bit is clear, the corresponding counter maintains its current value.
