AS5600L − Register Description

Non-Volatile Memory (OTP)

The non-volatile memory is used to permanently program the

configuration. To program the non-volatile memory, the I²C

interface is used (Option A, Option C). Alternatively, start and

stop positions can be programmed through the output pin

(Option B). The programming can be either performed in the

5V supply mode or in the 3.3V operation mode but using a

minimum supply voltage of 3.3V and a 10 μF capacitor at the

VDD3V3 pin to ground. This 10 μF capacitor is needed only

during the programming of the device. Two different

commands are used to permanently program the device:

Burn_Angle Command (ZPOS, MPOS)

The host microcontroller can perform a permanent

programming of ZPOS and MPOS with a BURN_ANGLE

command. To perform a BURN_ANGLE command, write the

value 0x80 into register 0xFF. The BURN_ANGLE command can

be executed up to 2 times. ZMCO shows how many times ZPOS

and MPOS have been permanently written.

This command will only be executed if the presence of the

magnet is detected (MD = 1).

Burn_Setting Command (MANG, CONFIG , I2CADDR)

The host microcontroller can perform a permanent writing of

MANG and CONFIG with a BURN_SETTING command. Once a bit

in those registers is permanent written to 1, it stays on 1and

cannot be changed to 0 anymore. A bit which is 0 can be

programmed to 1. To perform a BURN_SETTING command,

write the value 0x40 into register 0xFF.

MANG can be written only if ZPOS and MPOS have never been

permanently written (ZMCO = 00).
