PN532 CORE_INIT_RSP Field Value Questions

Hi,

 

I just started using PN7150 and want to understand some values in the CORE_INIT_RSP. The data is : 

 

CORE INIT RSP: 40 01 19 00 03 1e 03 00 08 00 01 02 03 80 81 82 83 02 d0 02 ff 02 00 04 88 10 01 a0

 

I have underlined the 4 bytes I am confused with. 

 

Byte 6: 1e, according to NCI 1.0, this is part of the NFCC features. 

All the NFCC bytes have upper 4 bits as 0. Why is there a 1 here? Shouldn't it be 0x0e?

 

Then the 0x81 0x82 0x83, I know 0x80-0xFE are for proprietary use, but in the user manual, only 0x80 is defnied 

 

What are the 0x81 0x82 and 0x83? And if they are some secrets, why bother putting it here anyway?

 

Thanks for your time and help in advance.

 

Best,

Z
