8.2.2 16-bit Write Command
These settings are temporary; they cannot be programmed permanently. The settings will be lost when the power supply is removed.
EN PROG command must be sent with a fixed 16-bit code (8CAE
ULP/LPn selects the Ultra Low Power Mode, when bit PSM is set: 0 = Low Power Mode, 1 = Ultra Low Power Mode
PSM enables power saving modes: 0 = normal operation, 1 = reduced power mode selected by bit ULP/LPn
HYS disables the hysteresis of the digital serial and PWM outputs:
DIS AGC disables the automatic gain control. The AGC will be frozen to a gain setting written in bits AGC 5:0 (D6:D1), bit FA must be set.
rst General Reset: 0 = normal operation, 1 = perform general reset (required after return from reduced power modes)
FA Freeze AGC; 0 = normal operation, 1= freeze AGC with the values stored in bits AGC 5:0. The PWM output will be invalid when bit FA is set.
8.2.3 18-bit OTP Read Commands
Note: To prohibit unintentional access to the OTP register, OTP PROG/write access is only enabled after the EN PROG command has been
EN PROG has not to be sent before a READ OTP.
During the 18bit OTP read/write transfer, each bit needs 4 clock pulses to be validated.
READ OTP reads the contents of the OTP register in digital form. The reserved area may contain any value
ANALOG OTP RD reads the contents of the OTP register as an analog voltage at pin PROG
sens reads the sensitivity setting of the Hall elements: 00 = low sensitivity, 11 = high sensitivity
zero position reads the programmed zero position; the actual angle of the magnet which is displayed as 000
