CLINT Timer Interrupt Demo

This demo (clintTimerInterruptDemo directory) shows how to use the core timer and its interrupt function. This demo configures the core timer for software interrupt and timer interrupt using CLINT driverwhere both interrupt triggered at different period. It prints messages on a terminal when the SoC is interrupted by the core timer.

For more detail of the driver, refer to Clint Timer Driver.

Newlib

By default, newlib-nano is used for this demo.
