5.2. Starting and Stopping
This section explains the starting and stopping.
The target event count is started by setting the FUNC[1:0] bits of the bus performance counter A control
register (BPCCRA) to a value other than "00". However, at this time the count starts from the current value
without initializing the bus performance counter A register (BPCTRA). The operation of the bus performance
counter stops when BPCCRA:FUNC[1:0] is set to "00".
