These bits are the Manufacturing ID (MID) for each IC. The contents of these bits cannot be read unless the
MID Read Enable bit (bit 5) is set in the Analog Control register (Reg 0x20). Enabling the Manufacturing ID
register (Reg 0x3C-0x3F) consumes power. The MID Read Enable bit in the Analog Control register (Reg
0x20, bit 5) should only be set when reading the contents of the Manufacturing ID register (Reg 0x3C-0x3F).
This register is read-only.
This register must be written with 0x41 after reset for correct operation
