20.3.5.24 KICK1R Register (offset = 70h) [reset = 0h]
KICK1R is shown in Figure 20-84 and described in Table 20-87.
The kick registers (KICKnR) are used to enable and disable write protection on the RTC registers. Out of
reset, the RTC registers are write-protected. To disable write protection, correct keys must be written to
the KICKnR registers. The Kick1 register allows writing to unlock the kick1 data and the kicker mechanism
to write to other MMRs. To disable RTC register write protection, the value of 83E7 0B13h must be written
to KICK0R, followed by the value of 95A4 F1E0h written to KICK1R.
