ENboolean
Enabled or not. If set to `false` pulses on `UPD` do not change the output value. Effictively that means the timer is paused. Set to `true` again to continue time counting.
Tsecnumber
Tick interval in second.
UPDpulse
Triggers the time value update.
TICKpulse
Pulses on each time interval end
