When synchronizing the timers using the GPTMSYNC register, the timer must be properly configured
to avoid glitches on the CCP outputs. Both the TnPLO and the TnMRSU bits must be set in the
GPTMTnMR register. Figure 10-6 on page 653 shows how the CCP output operates when the TnPLO
and TnMRSU bits are set and the GPTMTnMATCHR value is greater than the GPTMTnILR value.

Figure 10-7 on page 654 shows how the CCP output operates when the PLO and MRSU bits are set
and the GPTMTnMATCHR value is the same as the GPTMTnILR value. In this situation, if the PLO
bit is 0, the CCP signal goes high when the GPTMTnILR value is loaded and the match would be
essentially ignored.
