Time base transition events can be used to periodically collect information about processor activity. In
multiprocessor systems in which TB registers are synchronized among processors, time base transition
events can be used to correlate the performance monitor data obtained by the several processors. For this
use, software must specify the same TBSEL value for all processors in the system. Because the time-base
frequency is implementation-dependent, software should invoke a system service program to obtain the
frequency before choosing a value for TBSEL.
