Pulsein use Timer0

[Gigi]

The PULSEIN command uses a Timer or is implemented in software

[Anobium]

PULSEIN is a software implementation ( as follows ).

macro PulseIn (PulseInPin, PulseTime as Word, TimeUnit)
  PulseTime = 0
  Do While PulseInPin = On
    WaitL1 1 TimeUnit
    PulseTime += 1
    If PulseTime  = 0 Then Exit Do
  Loop
end macro

If your chip has Signal Measurement Timer ( SMT) then you can implement/use the SMT library ( there are demos for SMT).

OK, ok so it's not blocking either, i think it's fine for me.

I have an old 16F819 with no SMT I don't need great accuracy.
Thank you
