8.1 Steps

  1. Make sure ACTIVE_CELL has been set up for the desired number of channels.
  2. Enable TSREF by writing CONTROL2 = 0x01.
  3. Wait 6 ms for TSREF to fully enable.
  4. Write OT and UT thresholds for all GPIO inputs by writing OTUT_THRESH[OT_THR4:0 and UT_THR2:0].
  5. Configure which GPIO pin to sense by writing the GPIO_CONF1 to GPIO_CONF4 registers with each desired GPIO pin set as ADC and OTUT inputs
  6. Set OTUT mode to round robin, and set OTUT_GO to begin the OTUT protector by writing OTUT_CTRL = 0x03.
