The module also contains a kicker mechanism (see Figure 23-5) to prevent any spurious writes from changing the register values.
This mechanism requires two register writes to the KICK0 and KICK1 registers with exact data values before the kicker lock mechanism is released. Once released, the registers are writeable. The KICK0 data is 83E7 0B13h; the KICK1 data is 95A4 F1E0h. The mechanism remains in an unlocked state until a reset or invalid data pattern is written to one of the RTC_KICK0_REG or RTC_KICK1_REG registers.
