Allowed baudrates in T=CL (ISO 14443-4)
Use this register to let the H663 negotiate a baudrate greater than 106 kbit/s with ISO 14443-4
PICCs (DSI, DRI defined in PPS for ISO 14443 A, in ATTRIB for ISO 14443 B).
The H663 is theoretically able to communicate with PICCs at 848 kbit/s in both directions, but the
actual maximum speed depends heavily on the characteristics of the PICC, and on the coupler’s
actual maximum speed depends heavily on the characteristics of the PICC, and on the coupler’s
actual antenna and environment.

handle the higher baudrates without communication errors.
