Many of the ARM processors such as the Intel XScale have memory mapping and protection facilities. When enabled, the ARM restricts user mode applications from accessing various hardware facilities such as the coprocessor registers controling the memory mapping. Only system service routines running in privledged (supervisor) mode can access these facilities. Microsoft's Pocket-PC uses memory mapping and protection. Does PalmOs also use these ARM features?
If PalmOS does not use memory mapping and protection, is it safe to assume I can access the coprocessor registers and/or the watchdog timers via a PNOlet? Dave Koogler -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
