what is the max speed of the LPC flash for accessing?atmel say 30 MHZ for AT91sam7 device.i want to know if i have a jump in my code how many wait state i need to fetch new code?
The LPCs come with a “memory acceleration module (MAM)” that uses a 128-bit wide interface to the flash to fetch multiple instructions/data words at the same time. This prefetching allows operation at nearly zero-waitstate from flash, unless your code jumps a lot back and forth, rendering the prefretching useless.
