8.3 OTP Programming Connection
Programming of the AS5030 OTP memory does not require a dedicated programming hardware. The programming can be simply accomplished
over the serial 3-wire interface
For permanent programming (command PROG OTP, #19
(PROG).
For temporary OTP write (“soft write”; command WRITE OTP, #1F
To secure unintentional programming, any modification of the OTP memory is only enabled after a special password (command #10
sent to the AS5030.

8.3.1 Programming in Daisy Chain Mode
Programming in Daisy chain mode is possible for both 3-wire and 2-wire mode (see
write), no additional connections are required. Programming is executed with the respective programming commands. For permanent
programming, the programming voltage must be applied on pin#2 (PROG) of the device to be programmed. It is also possible to apply the
programming voltage simultaneously to all devices, as the actual programming is only executed by a software command.
A parallel connection of all PROG-pins allows digital programming verification but does not allow analog programming verification.
If analog programming verification is required, each PROG pin must be selected individually for verification.
