Level 0 Discovery header (48 bytes) exists at the head of Level 0 Discovery Data.
After the header, Feature Descriptor(s) are located.
Each Feature Descriptor has own Feature Code, for example, the code of TPer Feature is 1h, so you can find what type of feature descriptor is located right after.
According to the TCG spec[2][3][4][5][6][7][8], this data is interpreted as follows.
The content of length field is different from that of 970 EVO Plus.
