AltManufacturerAccess() provides a method of reading and writing data in the Manufacturer Access System (MAC). The MAC command is sent via AltManufacturerAccess() by a block protocol. The result is returned on AltManufacturerAccess() via a block read.
Commands are sent by writing to registers 0x00/0x01 or 0x3E/0x3F. 0x3E and 0x3F work the same as 0x00 and 0x01, but are primarily intended for block writes and reads.
Example: Send a MAC Gauging() to enable IT via AltManufacturerAccess().
Example: Read Chemical ID() (0x0006) via AltManufacturerAccess().
It is recommended to send “command only” operations to 0x00 and 0x01, and to set the command for a read back in the same way. The reason for this is that it can always reset any legacy support options that may be in effect; whereas, some legacy support options use 0x3E and 0x3F for other purposes. However, 0x3E and 0x3F can always safely be used for block reads. For backward compatibility, a request of the device number or version reports a value for a read on 0x00/0x01. The response word for the MAC commands DEV and VERSION (0x0001 and 0x0002) should report 0xFFA5 as the legacy response. This is meant as a token to indicate to the host that the real response is on the extended block. “Command only” operations take place immediately after the word write.
