For a full list of features supported by this IP, please refer AXI Timer product guide.
Two identical modules each timer/counter module having two 32/64-bit counters
The timer/counters support polled mode, interrupt driven mode, enabling and disabling specific timers, PWM operation and the cascade mode operation to get a 64-bit timer/counter
Support both increment and decrement counting
Ability to produce output in PWM by using the two timer/counters as a pair with a specified frequency and duty factor
Refer to the driver examples directory for various example applications that exercise the different features of the driver. Each application is linked in the table below. The following sections describe the usage and expected output of the various applications. These example applications can be imported into the Vitis IDE from the Board Support Package settings tab.
