8.3 Device Communication / Programming

Remark:

1. Send EN PROG (command 16) in normal mode before accessing the OTP in extended mode.

2. OTP assignment will be defined/updated.

Common mode voltage output enabled at COSN / CM pin (0...differential, 1...common)

gain

PGA gain setting (influences overall magnetic sensitivity), 2bit

dc_offset

Output DC offset (0…1.5V, 1…2.5V)

Hall_b

Hall bias setting (influences overall magnetic sensitivity), 6bit
