TDA4VM: [C7100 SE] What's the usage of PROMOTE flag in SE_FLAGS.

Part Number: TDA4VM

Hello there, 

Could you please make a detailed explaination on the PROMOTE flag in SE_FLAGS. and share a simple exmaple?

The training document shows this flag is "On-the-fly element promotion 8-bit to 16 bit, 8bit to 32 bit"

My understanding:

if input is 8 bit, PROMOTE = 8bit to float .SE will automatically change the output format to float.

Another related question:

if PROMOTE = 8bit to 16bit.  means input 0x08, output is 0x0008? or 0x08/256 * 65536?

if PROMOTE = 8bit to float or double, what's the quantization is?

Best Regards,

Samuel.
