3.5.14.1. System Counter

The CoreSight SoC-400 Timestamp Generator module provides a system counter to the Cortex* -A53 MPCore processor generic timers.

This system counter measures the passing of time in real-time. A 64-bit bus interface carries the system timer value to each CPU and this value is used as a basis for the four generic timers. The system timer operates in the cs_at_clk domain, which is typically configured by software to be 400 MHz.
