tmr imts works. I'm not thrilled with how the interrupts and modes are set... but I'm not sure what to do about it. The big problem is that I have to be in user mode to service irqs, but I can't enable and disable F and I in usermode. All I can do is an swi and then have handler which lets me enable or disable them (like a mini-syscall). 2009-04-22 18:55:40 +00:00			`#define enable_tmr_irq() (volatile uint32_t )(INTENNUM) = 5;`
