WebThe Cycle Counter Register counts the processor clock cycles. It is a 32-bit counter that can trigger an interrupt on overflow. You can use it in conjunction with the Performance Monitor Control Register and the two Counter Registers to provide a variety of useful metrics that enable you to optimize system performance.
