1. Overview
This section explains the overview of the bus performance counters.
This series has a built-in bus performance counters (BPC) for measuring the performance of the on-chip bus.
BPC measures the breakdown of traffic on the on-chip bus, and provides information for strategies to improve
bus performance. Because the counters do not count while the on-chip bus is idle, use the timers in the system
at the same time to measure the time.
