41.6.2.4.1 Stop Command
A Stop command can be issued from software by using Command bits in the Control B Set register (CTRLBSET.CMD = 0x2, STOP). When a Stop is detected while the counter is running, the counter will get set to bottom/top depending on the direction: up/down. All waveforms are cleared, and the Stop bit in the Status register is set (STATUS.STOP).
