Clear DTO (CDTO)
Disabled
Every time CDTO is set, the internal subcarrier DTO phase is reset to
0 and the RTCO output generates a logic 0 at time slot 68 (see
external document “RTC Functional Description” , available on
request). So an identical subcarrier phase can be generated by an
external device (e.g. an encoder).
