Timer0: is my thinking correct??

[Guest]

Hi All,

I am using a 12F629 device with the internal 4 MHz oscillator. With this configuration, I believe that each clock cycle is 1 us, and thus the Timer0 can potentially increment every 4 us (Fosc/4). Is that correct?

Then if I further prescale this value by 16, the actual timer increment period
is 64 uS (16 X 4 uS).

Am I thinking about this correctly, because I'm getting consistently strange results when I try to use Timer0 to measure the duration of a known pulse width.

[code}

setup_counters( RTCC_INTERNAL, RTCC_DIV_16 );

[/code]

Thanks,
