I'm having troubles deciphering the datasheet for the DS3231 RTC. The below table shows that 0x02 bit 6 is the flag to operate in 12- or 24-hour mode. But which one correspond to the bit being low or high? I assume the line above the 24 must tell it, but I guess I lack knowledge of the usual conventions.
