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

ULP/LP

n 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:

0 (default) = 1-bit hysteresis, 1 = no hysteresis

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

sent. OTP access is locked again by sending a RD ANGLE or SET PWR MODE command.

EN PROG need 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
