'''
This decoder stacks on top of the SPI PD and decodes the st25r39xx High performance NFC universal device and EMVCo reader protocol (SPI mode).

It has been successfully tested with the st25r3916, other chips of this family may or may not be fully supported but not been verified.

Please note that the SPI interface uses clock polarity 0 and clock phase 1, which is not the default setting.
