Thread: XTAL startup issues on PIC 73B
face BY : Andrew Kunz email (remove spam text)

I've heard there are many reports on the '73B (and '77 and F87x) having problems
starting up crystals.

We have had to go to HS mode even with 4.000 MHz crystals.

Haven't had problems on my products with ceramic resonators, though.
