Memory Address Space Mapping

The registers are assigned to following memory spaces:
Adress (hex)
0000 Status
Bit 0: Error
Bit 1: Busy
Bit 3...2: Reserved
Bit 6...4: Stop detected
Bit 7: Stop overflow
Bit 31...6: Reserved
0004 Result position 1
0008 Result position 2
000C Result position 3
0010 Result position 4
003C Config
Bit 2...0: Num of magnets
Bit 31...3: Reserved
Tab. 6-1: Memory assignment
Description of Status register:
– Error: This bit is set if the number of detected stops is
less than the number of magnets entered in the Config
register.
– Busy: This bit is always 0.
– Stop detected: This bit field indicates the number of
magnets. For example, "001" means that 1 stop was
detected.
– Stop overflow: This bit is mapped if the number of
detected stops is more than the number of magnets
entered in the Config register.
– Reserved bits (bit 2, bit 3) in LSB are always 0.
