"WebThe RTC module uses two registers to generate 1 Hz signal, feeding the rest of counters on the module: the RTCMOD and RTCCNT. The RTCCNT is a simple 16-bit up counter that counts at the rate of the RTCCLK. The RTCCLK depends on the clock source selected previously. The RTCMOD register acts, as its name states, as a modulo register that sets … " - Sets the rtc counter value

WebThis was especially fortunate as it turned out that the firmware on the CRD does not allow updating the UEFI RTC offset even if this works on the X13s. As the benefit of sharing the RTC offset with the UEFI firmware (and Windows) is rather small (e.g. to make sure they never get out sync), I instead opted for using the PMIC registers on both machines.
