HELP! PIC18F8722 ****t F Input Problem

by GaryI <gary.ireland@[EMAIL PROTECTED] > Feb 19, 2008 at 03:51 AM

Hi,



I'm using the 18f8722.  What I've noticed is that when I power up the
device and try to read ****t F, I do not get anything back from pin 7
until after a few seconds of waiting. The circuit is fine, and the
****t f pin 7 works fine on some hardware and this problem occurs on
other.  There's some kind of pic hardware issue with the functionality
of using pins 5/6/7 on ****t f.  I've done some testing and debugging
by moving lines to different pins but I've noticed that there's some
'correlation' between pins 5/6/7 on ****tf.



It all points towards a silicon issue possibly with the pic and has
yet to be re****ted by Microchip.  There's no info on the Silicon
Errata datasheets.



Help greatly appreciated!



Regards,
