Dear Friends. I am using LPC 2138 (ARM) processor. I am using its flash memory to store large data. I want to measure exact time, processor requires to complete whole write operation. To do this can any one tell me how to make use of onchip hardware timers [Timer0 or Timer1] to measure require to complete such write operation. Please note I am new to hardware Timers. - Thanks in advace Raj Mittal
