You can't change the microcode of the PALM processor. That would be like
changing the microcode of e.g. a MC68000.
Actually....you can do that.
The IBM {PC,XT,AT}/370 card(s) (ISA-bus card that put a "baby" IBM S/370 on
your desktop) had a CPU that was a re-microcoded 68000 (emulating some
subset of the IBM S/370 mainframe instruction set). IBM licensed the
architecture from Motorola. Probably got familiar with it building the IBM
9000 Instruments System.
That, of course, doesn't mean you could do it on a PALM.
