Does ZBasic have the capability to handle the Pin Change interrupts that are available of the M644 processor used in the ZX-24A?

Ah, excellent.
Is there any protection from enabling PCInts on the pins that run the SPI bus?
I suppose there MIGHT be some use to having an interrupt occur on SPI activity, but I really doubt it.

None whatsoever. Nor is there any protection from enabling a pin change interrupt any other pin that is an output. That may be useful, effectively implementing a "software interrupt". |

I have used those "software" interrupts on several occasions. Very useful.
