1. (Minor observation):
The documentation says (p80, manual1):
When downloading new programs, you must ensure the
correct frequency (View>Options>Mode) is used to match the last program
running in the PICAXE chip. If in doubt perform a ‘hard-reset’ at 4Hz.
I think it can download a new program to my 14M no matter whether it was last running at 4 or 8MHz.
2. (Major question):
If I have a 28X1 and use a resonator (or external xtal clock oscillator??) faster than 4MHz, does "setfreq m4" always set it to the frequency of the resonator, while 'setfreq m8" sets it to twice the frequency? Otherwise, should I get an 8 or 16MHz resonator if I want 16MHz (I presume that a device that is capable of 20MHz should not actually be run at 20 because I'd never be able to program the thing?? I notice the speed selector disappears when selecting 28X1 parts in View->Options->Mode, so I'm a bit confused as to what is supported in the way of downloads... page 68 of the manual doesn't help me see what can be done).
