Hi Allen - The Dec 20 A5 schematic I have shows 10K to VB_SYS for these. If they really are 100K, it makes the "crazy" waveform I found a bit easier to imagine. > For EXTON, I found the PMU something has rising and falling edge > detected on EXTON1-3.

Yep, sounds good. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFHqBW6OjLpvpq7dMoRAnRJAJ9neVyiSLGU4K68HiBPpgBQ50j8mACfec+Y SuyudknLyos9F7+4LhgC15g= =uMwA -----END PGP SIGNATURE-----
