The following high-level steps detail the how to load a configuration. For complete details, see the Renesas RC38612 datasheet.

  1. Set the required CONFIG Value on JITT1_GPIO0-GPIO3 (for example, Config 15 – 1111 or Config 14 – 1110).
  2. Assert JITT_RESETn to logic 0 (resets the RC38612 devices).
  3. Give some delay (> 10 ms).
  4. Assert JITT_RESETn to logic 1 (gets the RC38612 devices out of reset).
  5. Monitor JITT1_GPIO5. JITT1_GPIO5 asserted to logic 1 indicates that the TX clocks generated by the RC38612 devices are in sync with the recovered clock.
