Hibernation Lock (HIBLOCK)
Writing 0xA3359554 to the HIBLOCK register enables write access to the HIBRTCLD, HIBCALLD0, HIBCALLD1 and Tamper registers. Writing any other value to the HIBLOCK register re-enables the locked state for register writes to all the other registers. Reading the HIBLOCK register returns the lock status rather than the 32-bit value written. Therefore, when write accesses are disabled, reading the HIBLOCK register returns 0x00000001 when locked; otherwise, the returned value is 0x00000000 (unlocked).
HIBLOCK is shown in Figure 6-28 and described in Table 6-23.
