9.1.4 OTP Default Setting
The AS5245 can also be operated without programming. The default, un-programmed setting is:
9.1.5 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.
Table 13. Redundancy Addressing
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.
