Hello,

i found in the data sheet that if i use the 64MHz frequency i need to add 1 wait state to the xFLASH, 2 wait states for the XRAM1/2, but what about the iFLASH and iRAM i could not find any data to them, can i assume that they work with 0 wait states?

thanks,

Uri.

Hello,

IFLASH and IRAM (Non XBUS peripherals in general) don't need Waitstates.

The IFlash module offers a fast access time, allowing zero wait-state access with CPU frequency up to 64 MHz.

XFLASH and XRAM need waitstates because they are seen as external peripherals even they are internal.

Regards,

Najoua.
