OTP Default Setting
The AS5245 can also be operated without programming. The default, un-programmed setting is:
-
-
-
-
-
9.1.5
Output Md0, Output MD1: 00= Default mode
Z0 to Z11: 00 = no programmed zero position
CCW: 0 = clockwise operation
RA4 to RA0: 0 = no OTP bit is selected
MagCompEN: 1 = The green / yellow mode is enabled.
Redundancy
For a better programming reliability, a redundancy is implemented. This function can be used in cases where the programming of one bit fails.
With an address RA(4:0), one bit can be selected and programmed.

9.1.6
Redundant Programming Option
In addition to the regular programming, a redundant programming option is available. This option allows that one selectable OTP bit can be set
to “1” (programmed state) by writing the location of that bit into a 5-bit address decoder. This address can be stored in bits RA4…RA0 in the OTP
user settings.
Example: setting RA4…0 to “00001” will select bit 51 = PWhalfEN_Indexwidth, “00010” selects bit 50 = MagCompEN, “10010” selects bit 34
=CCW, etc.
