AM6442: Dose AM64x DDR subsystem allowed 32-bit LPDDR4?

Part Number: AM6442

Tool/software:

Hi

May I have question about AM64x DDR subsystem?

I want to use LPDDR4 for AM64x, but some memory supplyer not recommanded 16-bit bus wides.

So I want to use 32-bit LPDDR4 with Data 16 to 31 bit non-connected. 

Is this rayout allowed?

Thanks,

GR
