14-BIT ABSOLUTE ANGLE HALL ENCODER
The BSEL register is used to switch to other memory
banks on the external EEPROM. After an iC-MHM pow-
er-on, bank 0 is selected, which mirrors the internal
registers of iC-MHM. If BSEL points at a higher memory
bank, the addresses 0x00 - 0x3F are mapped and aim
at higher EEPROM registers.
