PS re "the SILabs chips have an excellent interanl watchdog" I have found that the internal watchdogs work well on chips with a large analog content and not too well on chips with no/very little analog content. I guess this is due to "when doing analog anyhow" to include a good supervisor is simple, if you have to add this analog function to an otherwise digital chip, you take shortcuts. The watchdogs are great, but when you run the F120 at Full Tilt Boogie, you find yourself petting the dog more often than you'd like. The timer is 21 bits wide in all of the SiLabs parts I've used, and 21 bits at 98 MHz is 20 ms, so there it is. -a |
