pulsein question (units of measure?)

[nomad]

Actually the manual gives the resolution, but does not specify the units of measure.
(I've read the manual)

The resolution of PULSIN is dependent upon the oscillator frequency. If a 4MHz oscillator is used, the pulse width is returned in 10us increments. If a 20MHz oscillator is used, the pulse width will have a 2us resolution. Defining an OSC value has no effect on PULSIN. The resolution always changes with the actual oscillator speed.

they probably could clarify that part a bit.
Thanks for your reply.

Edit: that 40/fOsc should come in handy when I cannot find a standard crystal. ( Have lots of 10.24Mhz etc lying about) Thanks
