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