Simulating 14443-4 Card

Hi, guys?

(First My English is awkward. Sorry.)

I am studying about simulation of 14443-4 card.
Especially, interested in Java CARD.

So I have tried the simulation using proxmark3(r839 version).
And I used ACR122U as a reader.

Proxmark3 Command : hf 14a sim 4 12345678
ACR122u Command : nfc-list

Result is the below.

ATQA (SENS_RES): 00  04 
UID (NFCID1): 12  34  56  78 
SAK (SEL_RES): 28 
ATS: 58  00  02
----------------------------------------------------------

But I want a Result the below.(I hope to change ATS value)

ATQA (SENS_RES): 00  04 
UID (NFCID1): 12  34  56  78 
SAK (SEL_RES): 28 
ATS: 78  80  83  02  4a  43  4f  50  34  31  56  32  33  32

Please How do I can do let me know.

Thank you.

P.S.
And add as possible, I hope to know how to change ATQA, SAK, ATS freely.
