AS5170 − Register Description

Figure 21 and Figure 22 show examples of read and write.

Figure 21:

Example of Write (Reg[0x22] = 0x18, Reg[0x23] = 0xA2)

Figure 22:

Example of Read (Reg[0x2B], Reg[0x2C])

Exiting Communication Mode

Communication mode is exited and operational mode is

entered with a Pass-to-function (P2F) command, by writing to

the virtual registers 0x60 and 0x61:

P2F: write(0x60) = 0x70, write(0x61) = 0x51

No more commands can be sent after sending this command,

because the device is permanently placed in operational mode.

Burning the OTP Registers

The BURNOTP command writes the OTP registers with their

programmed values. The command is issued by writing to

virtual registers 0x62 and 0x63:

BURNOTP: write(0x62) = 0x70, write(0x63) = 0x51

Customer ID

A specific identifier chosen by the user can be stored in the

non-volatile memory. This identifier consists of 4 bytes and can

be stored in the locations CUSTID0, CUSTID1, CUSTID2, and

CUSTID3.
