16.1 0x00 ManufacturerAccess() and 0x44 ManufacturerBlockAccess()

ManufacturerBlockAccess() provides a method of reading and writing data in the Manufacturer Access System (MAC). This block MAC access method is standard for the BQ40Zxy family. The MAC command is sent via ManufacturerBlockAccess() by the SMBus block protocol. The result is returned on ManufacturerBlockAccess() via an SMBus block read.

Example: Send a MAC Gauging() to enable IT via ManufacturerBlockAccess().

With Impedance Track™ disabled, send Gauging() (0x0021) to ManufacturerBlockAccess()
1. SMBus block write. Command = 0x44. Data = 21 00 (data must be sent in little endian)
IT is enabled, ManufacturingStatus()[GAUGE_EN] = 1.

Example: Read Chemical ID() (0x0006) via ManufacturerBlockAccess().

Send Chemical ID() to ManufacturerBlockAccess().
1. SMBus block write. Command = 0x44. Data sent = 06 00 (data must be sent in little endian)
Read the result from ManufacturerBlockAccess().
1. SMBus block read. Command = 0x44. Data read = 06 00 00 01 (each data entity is returned in little endian).
2. The first 2 bytes, “06 00”, is the MAC command.
3. The second 2 bytes, “00 01”, is the chem ID returning in little endian. That is 0x0100, chem ID 100.

For backwards compatibility with the bq30zxy families, sending MAC commands via ManufacturerAccess() (0x00) as well as the returning data on ManufacturerData() are supported in BQ40Z50-R4.

Note: Note that MAC commands are sent through ManufacturerAccess() (0x00) by an SMBus write word protocol. The result reading from ManufacturerData() does not include the MAC command.

Example: Send a MAC Gauging() to enable IT via ManufacturerAccess().

With Impedance Track disabled, send Gauging() (0x0021) to ManufacturerAccess().
1. SMBus word write. Command = 0x00. Data = 00 21 (Data to address 0x00 is big endian.)
IT is enabled, ManufacturingStatus()[GAUGE_EN] = 1.

Example: Read Chemical ID() (0x0006) via ManufacturerAccess().

Send Chemical ID() to ManufacturerAccess().
1. SMBus word write. Command = 0x00. Data sent = 00 06 (data to address 0x00 is big endian).
Read the result from ManufacturerData().
1. SMBus block read. Command = 0x23. Data read = 00 01 (each data entity is returned in little endian).
2. That is 0x0100, chem ID 100.

The ManufacturerAccess() and ManufacturerBlockAccess() are interchangeable. The result can be read from ManufacturerData() or ManufacturerBlockAccess(), regardless of how the MAC command is sent.
