• BCPB: TIOB Compare B
These two bits determine the effect on the TIOBx output pin caused by an equal comparison between the counter and the
Compare Register B value. These bits are active only if TIOBx is not an input (see “EEVT[1:0]: External Event” of the
Mode Register in Waveform Mode” on page
where xxx = CPB.
Note:
• BCPC: TIOB Compare C
These two bits determine the effect on the TIOBx output pin caused by an equal comparison between the counter and the
Compare register C value. These bits are active only if TIOBx is not an input (see “EEVT[1:0]: External Event” of the
Mode Register in Waveform Mode” on page
where xxx = CPC.
• BEEVT: TIOB External Event
These two bits determine the effect on the TIOBx output pin caused by an external event. The external event source is
selected by EEVT[1:0] of the mode register. These bits are active only if TIOBx is not an input (see “EEVT[1:0]: External
Event” of the
ware Trigger” where xxx = EEVT.
• BSWTRG: TIOB Software Trigger
These two bits determine the effect on the TIOBx output pin caused by a software trigger. These bits are active only if
TIOBx is not an input (see “EEVT[1:0]: External Event” of the

If several events that control TIOBx output (set, clear or toggle) arrive at the same time, only one has an action according to the
following priority:
1. BSWTRG (highest priority)
2. BEEVT
3. BCPC
4. BCPB
