The second byte after the configuration command is in the following format:
The above example shows the HH, MM, SS digits on a 10-digit display panel when RTC
digit 1 is configured (Bits b7 - b4= “0000”) & HH:MM:SS format is selected with separator
being a part of the same digit. The MSB of Hour corresponds to Digit 1 when
b7 - b4= “0000”.
When b7-b4=“0001” is configured, the MSB of Hour starts from the Digit 2.
The Digit 1 must start from the left.
