Preliminary Product Specification
Undefined register addresses must not be written to; incorrect behavior may be the result.
Unused register bits (blank table cells) must be set to '0' when programming the registers.
All registers can be written to while the chip is in power down.
*) These registers requires a power down cycle when written to (See Startup Initialization).
