Figure 34-62 shows the associated timing waveforms for this configuration. Here, TBPRD = 600 for both
master and slave. For the slave, TBPHS = 200 (200/600 × 360° = 120°). Whenever the master generates
a SyncIn pulse (CTR = PRD), the value of TBPHS = 200 is loaded into the slave TBCTR register so the
slave time-base is always leading the master's time-base by 120°.
