20. Serial PROM Mode
20.4 Interface Specifications for UART
T
5CL8
Note 1: “Ref. Frequency” and “Rating” show frequencies available in the serial PROM mode. Though the frequency is supported
in the serial PROM mode, the serial PROM mode may not be activated correctly due to the frequency difference in the
external controller (such as personal computer) and oscillator, and load capacitance of communication pins.
Note 2: It is recommended that the total frequency difference is within
±
3% so that auto detection is performed correctly by the ref-
erence frequency.
Note 3: The external controller must transmit the matching data (5AH) repeatedly till the auto detection of baud rate is performed.
This number indicates the number of times the matching data is transmitted for each frequency.
