Hello everyone,

I have 2 questions regarding the chip Intel XScale 270 used in many Pocket
PCs.

When the global interrupt flags (FIQ & IRQ) are disabled, are the hardware
breakpoints set by the debug unit still effective or ignored?

Does turning on/off the debug Global Enable bit (bit 31 of DCSR) affect the
internal working of the Core in term of execution time of the instructions?

Thanks sincerely,
Arintel
