| 12 | description: | |
| 13 | The system counter(sys_ctr) is a programmable system counter |
| 14 | which provides a shared time base to Cortex A15, A7, A53, A73, |
| 15 | etc. it is intended for use in applications where the counter |
| 16 | is always powered and support multiple, unrelated clocks. The |
| 17 | compare frame inside can be used for timer purpose. |
