Figure 14. Analog OTP Verification
Redundancy Decoding
If a bit is not fused properly (analog readout levels violated), the redundancy bits can be used as shown in the table
below. Only one single bit can be overwritten with a logic HI. An improper fusing cannot be made undone.
Table 12.
Multi Turn Counter
An 8-bit register is used for counting the magnet’s revolutions. With each zero transition in any direction, the output of
a special counter is incremented or decremented. The initial value after reset is 0 LSB.
The multi turn value is encoded as complement on two. Clockwise rotation gives increasing angle values and positive
turn count. Counter clockwise rotation exhibits decreasing angle values and a negative turn count respectively.
