12.2.5.4 Output Example — Timer in Up/Down Mode
The OUTx signal changes when the timer equals TACCRx in either count direction and when the timer
equals TACCR0, depending on the output mode. An example is shown in Figure 12-14 using TACCR0
and TACCR2.

NOTE: Switching Between Output Modes
When switching between output modes, one of the OUTMODx bits should remain set during
the transition, unless switching to mode 0. Otherwise, output glitching can occur because a
NOR gate decodes output mode 0. A safe method for switching between output modes is to
use output mode 7 as a transition state:
BIS #OUTMOD_7,&TACCTLx ; Set output mode=7
BIC #OUTMODx, &TACCTLx ; Clear unwanted bits
