How to set the sensitivity of this AS3992 reader?

This function sets and reads various gen2 related settings.
The values are only being set if the proper set_ value is set to 1.
1-2
Values for the different parameters are:
3-6

For example,
send: 59 0E 00 00 00 00 00 00 00 00 00 00 00 00, we can get the default values of gen2 parameters.

The default sensitivity value of our reader is -71dBm, which is 0xB9 in the computer.
71 -> 01000111B, -71 -> 10111001B -> 0xB9

Note: The largest sensitivity of AS3992 is -86dBm (0xaa).

The other gen2 parameters,
6

Now I set the sensitivity -54dBm. Send: 59 0E 00 00 00 00 00 00 00 00 00 00 01 CA
