IWR6843: The parameters of IWR6843

Hi all

i can set the RF parameters of IWR6843. For example. i set the sample data number is 128 and the chirp number is 64.

just as below

profileCfg 0 60.6 100 7 40 0 0 82 1 128 5300 0 0 48
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
chirpCfg 2 2 0 0 0 0 0 4
frameCfg 0 2 64 0 50 1 0

I want to increase the data number or the chirp number. but i want to know the upper limit of them

I read some application notes of TI but not find the answer

Look forword for your help.

Thanks
