Struct cc13x2_cc26x2_hal::cpu_dwt::CYCCNT

pub struct CYCCNT { /* fields omitted */ }

Current PC Sampler Cycle Count This register is used to count the number of core cycles. This counter can measure elapsed execution time. This is a free-running counter (this counter will not advance in power modes where free-running clock to CPU stops). The counter has three functions: 1: When CTRL.PCSAMPLEENA = 1, the PC is sampled and emitted when the selected tapped bit changes value (0 to 1 or 1 to 0) and any post-scalar value counts to 0. 2: When CTRL.CYCEVTENA = 1 , (and CTRL.PCSAMPLEENA = 0), an event is emitted when the selected tapped bit changes value (0 to 1 or 1 to 0) and any post-scalar value counts to 0. 3: Applications and debuggers can use the counter to measure elapsed execution time. By subtracting a start and an end time, an application can measure time between in-core clocks (other than when Halted in debug). This is valid to 2^32 core clock cycles (for example, almost 89.5 seconds at 48MHz).
