Best Practice for Displaying Binary Flags

[bbean-LV]

We have a 16 bit register telemetry item that could be defined as:
APPEND_ITEM FAULT_FLAGS 16 UINT "Flags indicating fault status"

We need to display the individual bits in this register on a screen (probably using LEDs) AND still retain the FAULT_FLAGS 16 bit value for display/storage as separate item. What's the best way to break out the bit values for LED display while still retaining/storing the 16bit register item value?

The register could be broken down into quantity 16 - 1 bit items as below, but we would lose the 16value in other displays the FPGA guys want to see.
APPEND_ITEM FAULT_FLAG_0 1 UINT "0 Bit status led"
APPEND_ITEM FAULT_FLAG_1 1 UINT "1 Bit status led"
APPEND_ITEM FAULT_FLAG_2 1 UINT "2 Bit status led"
APPEND_ITEM FAULT_FLAG_3 1 UINT "3 Bit status led"
.......

could something like this work (haven't been able to test yet but will):
APPEND_ITEM FAULT_FLAGS 16 UINT "Flags indicating fault status"
APPEND_ITEM FLAG0 0 DERIVED
GENERIC_READ_CONVERSION_START UINT
((packet.read('FAULT_FLAGS') >> 0) & 1) #Right shift the value by desired bit location and AND with 1
GENERIC_READ_CONVERSION_END
APPEND_ITEM FLAG1 0 DERIVED
GENERIC_READ_CONVERSION_START UINT
((packet.read('FAULT_FLAGS') >> 1) & 1) #Right shift the value by desired bit location and AND with 1
GENERIC_READ_CONVERSION_END

Another nice to have would be to put this in a separate configuration file. I was looking into "SELECT" features but couldn't find enough documentation on it.
SELECT_TELEMETRY SYSTEM REGISTERS
SELECT_ITEM FAULT_FLAGS

You can define overlapping telemetry items using the ITEM keyword and defining the bit offset explicitly. This can go right inline with the current packet definition or moved to another file using SELECT_TELEMETRY and then just declaring the new items under that (again using ITEM).

Thank you!
Is there anyway to do this by reference to the telemetry item instead of explicitly by bit offset. During FPGA development, developers add and shift their location often. We have a number of these bitwise fault registers in the telemetry and updating all the explicit offsets every time the telem changes is somewhat painful.
eg something like this doesn't seem to work

SELECT_TELEMETRY SYSTEM REGISTERS
SELECT_ITEM FAULT_FLAGS
   ITEM FAULT15 -15 1 UINT "FAULT15 Flag"
   ITEM FAULT14 -14 1 UINT "FAULT14 Flag"
.....

You could write a partial that you include which defines the variable part of the packet. See the demo and how we include _ccsds_cmd.txt. Then you could even potentially create a script that dynamically creates this file based on your FPGA definition.
