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 document “RTC Functional
Description”, available on request). So an identical
subcarrier phase can be generated by an external device
(e.g. an encoder); if a DTO reset is programmed via
CDTO it has always to be executed in the following way:
1. Set CDTO = 0
2. Set CDTO = 1.
