Lowest readable input voltage?

[droptail]

I forgot what the lowest input voltage can be for the charging caps in a 16F716 to count using the PULSIN command?

Thanks

To be seen for the PULSIN command, the signal will need to exceed the input threshold voltage for that pin. This will be approx 2/3 Vcc for a Shmidt trigger input, 1.2 volts for a TTL input and for analog you can set your own limits.
