INE COUNTER THRESHOLDS
For the events related to the line counters of the source and the target, (either HPS or BRS) there are two thresholds for
each task in the HBI threshold register (see Table 35). The purpose of this register is to set the HS or HT event flag when
the corresponding line counter has reached the threshold. These thresholds must be written before waiting on the event.
A value of zero as threshold turns the HS or HT event on, for every line.
