Notes:
1. Any register not listed here is reserved and must not be written. The result of a read operation on these bits is
undefined.
2. Except where noted, reserved register bits will always read back as “1,” and are not affected by write operations. For
future compatibility, it is recommended that prior to a write operation, registers should be read. Then the values read
from the RSVD bits should be written back unchanged during the write operation.

The minimum recommended operating voltage is 1.9 V. A transi-
tion of the VDD status bit from 0 to 1 indicates that VDD is
between 1.8 V and 1.9 V. If the VDD drops below 1.8 V, the
device will no longer operate correctly.
