Hai!
I am using LCP2378 controller.here i m using 12Mhz clock externally(Controller runs at 48Mhz speed by enabling PLL related Regs.).
Pls tel what is the interrupt latency time for IRQ and FIQ.
For FIQ how much fast interrupt latency is??
Thanks in advance
interrupt latency on an ARM with a VIC depends on interrupt source priority, whether interrupts are enabled at all, IRQ or FIQ, and of course the electrical properties of your chip - for that information you would have to consult your data sheet.
