ENboolean
Enabled or not. If set to `false` pulses on `UPD` do not change the output value. Effectively that means the timer is paused. Set to `true` again to continue time counting.
RSTpulse
Resets the current time value to zero.
UPDpulse
Triggers the time value update.
OUTnumber
The current time value in seconds.
