Does anyone have an idea of whether the PIC32MZ (200 Mhz)
can process interrupts at 4 Mhz?
That's minimum. But what about 20 MHz?
With some "minimal (small-ish) amount of processing" for each interrupt sequence.
I want to fully emulate a CDP1802 microprocessor at chip-pin-signal level,
and I was thinking about running the XTAL clock pin
for the emulated chip as an interrupt of the PIC32MZ.
That way I could run it as a really fast 1802 (hopefully)
and also have it be plug-compatible so that it could be
used in any 1802 computer. (these mostly run at < 4 MHz)
I do need one to run VERY fast, at at least 20 MHz,
but that could be a mode -- "Run All Out".
If anyone has a suggestion for a better microcontroller to use,
PIC or other, I'm open to whatever.
TIA
