Note 1: “Ref. Frequency” and “Rating” show frequencies available in the serial PROM mode. Though the frequency is supported
Note 2: It is recommended that the total frequency difference is within ±3% so that auto detection is performed correctly by the ref-
Note 3: The external controller must transmit the matching data (5AH) repeatedly till the auto detection of baud rate is performed.
