(0x00 - 0x0E, other values RFU) When

there is PP, MM must also be provided.

These 9 bytes are optional. Default

value of PP:MM:DD is 0 and

corresponds to FWT ~302µs.

FWT = (2^PP)*(MM+1)*(DD+128)*

32/13.56 µs

7:0

DD (0x00 - 0x7F, other values RFU)

7:0

TTTT (Optional)

TR0 = TTTT/FC (LSB first),

default 1023 = 0x3FF

7:0

YY (Optional)

PCD Min TR1 (Min_TR1 = 8 * XX / fS),

default = 0

7:0

ZZ (Optional)

PCD Max TR1 (Max_TR1 = 8 * ZZ / fS),

default = 26 = 0x1A
