TMP1826: Getting 256 unique IDs based on IO and resistor value

Part Number: TMP1826

Hello engineers,

Could you verify the following:

If one would like to get 256 unique ID's based on hardware then the following steps need to be followed:

  1. Read the scratchpad
  2. Modify the scratchpad such that FLEX_ADDR_MODE='01b'
  3. Calculate the CRC of the modified scratchpad
  4. Write the modified scratchpad to the device
  5. Read the scratchpad again and save SHORT_ADDRESS[3:0]
  6. Modify the scratchpad such that FLEX_ADDR_MODE='10b'
  7. Calculate the CRC of the modified scratchpad
  8. Write the modified scratchpad to the device
  9. ? 'place the device in shut down mode' ?
  10. Wait 2.8ms
  11. Read the scratchpad again and save SHORT_ADDRESS[3:0]

Step 9 is what I'm struggling with, what is shut down mode?

With regards,
Roy
