LP5569: LED052509 Compiler: maxmum map data value is 1ffh(111111111b)

Part Number: LP5569

Tool/software:

I'm trying to get the execution engine to map to the master fader which the data sheet says is possible.

I'm getting the above error message when I use the "dw 0000001000000000b" instruction:

At Line 2 [ERROR] Invalid argument
[Code] dw 0000001000000000b
maxmum map data value is 1ffh(111111111b)

Should the compiler allow this value? Is there an update to the compiler that supports this?

I am using the software called LP5569 EVM.

If the command dw 0000001000000000b is used (bit 9 is set) the following error is shown:

At Line 2 [ERROR] Invalid argument
[Code] dw 0000001000000000b
maxmum map data value is 1ffh(111111111b)

The data sheet say I need to use Bit[9] to have the execution engine control it's master fader:
