Description
### Description
Currently, I configured my Nuttx with 1000Hz as scheduler tick.
The SOC has a clock running at 10MHz, so I am wondering how to support sleep in micro-second in this SOC: shall I enable HRTimer in Nuttx, shall I provide lower-level HRTimer driver support?
### Verification
- [x] I have verified before submitting the report.

Research direction
Start by reading NuttX's scheduler tick and HRTimer support, then examine how microsecond sleep would interact with the 1000Hz configuration and the SoC's 10MHz clock. Confirm whether existing HRTimer support is sufficient or whether lower-level driver work is required; done means a documented, concrete implementation path.
