NOTE

Failure to comply with the preceding two statements may result in unexpected device

behavior.

7.6.1.1 Register Usage

All registers, except the Command Register (CMD), operate in the same manner. For all registers except CMD,

reading will return the value stored in the addressed register, and writing will store a new value into the

addressed register.

The Command Register (CMD) is a special register that accepts commands. A value written to CMD causes the

bq76PL455A to carry out a specific action and this may include the generation of a response from the

bq76PL455A. For example, a Synchronous Sample command written to CMD causes a response that contains

the conversion values for any selected channels.

NOTE

New commands should not be written until the current command is complete and any

requested response has been received in its entirety, or a timeout has occurred.

All unused bits in the registers should always be written as 0, unless otherwise noted.

The register space is byte-addressable. Reads or writes can cover any number of bytes. Multi-byte registers (16-

bit or 32-bit, and so forth) can read them as individual bytes, one at a time, or as a single register. The most-

significant byte of multi-byte registers is stored at the lower address.

User firmware should not write to register addresses shown as "RESERVED" and addresses not shown in
