Writing to a volatile register is nearly instantaneous. Writing to a non-volatile register, however,
takes typically 16 ms. Because the packet size can vary based on the need for encoding, there
are two possible packet structures. The following tables show the byte sequences for writing a
register in each case.
WARNING:
the register write. Loss of important configuration information could occur if the unit loses power
during a non-volatile write cycle.
Table 9, Write Register Command, value to be written is less than 128 (0x80).
