An OTP bit location addressed by this address is always set to “1” independent of the corresponding origi- nal OTP bit setting. 7.6.3 OTP Default Setting The AS5140H can also be operated without programming. The default, un-programmed setting is as listed below. - Md0, MD1:00 = Incremental mode = quadrature. - Div0, Div1:00 = Incremental resolution = 10bit. - Index:0 = Index bit width = 1LSB. - Z9 to Z0:00 = No programmed zero position. - CCW:0 = Clockwise operation. - RA4 to RA0:0 = No OTP bit is selected. 7.6.4 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 RA5...0 in the OTP user settings. Example: Setting RA5…0 to “00001” will select bit 51 = MD0, “00010” selects bit 50 = MD1, “10000” selects bit 36 = CCW, etc. 7.6.5 OTP Register Entry and Exit Condition To avoid accidental modification of the OTP during normal operation, each OTP access (Load, Write, Read, Program) requires a defined entry and exit procedure, using the CSn, PROG and CLK signals as shown in Figure 14. 17 ChipID0 18 bit Chip ID 16 ChipID1 :: 0 ChipID17 mbit0 Factory Bit Table 19.
