Notes
1. x = don’t care
2. ID1 will always return 0; ID2 will always return 1.
3. If the factory defaults OTP bit has been programmed to logic 1, then the Set factory defaults instruction is ignored
4. These bits are used to write data to the OTP shift register when in calibration mode. ID1 = write ‘0’; ID2 = write ‘1’.
