1 7:0 PP (max 14, i.e. 0x0E)
Examples of commands
02020301 – ISO/IEC14443B, 106kbps
transmission & reception, Frame Waiting Time
(FWT) of 302µs, CRC automatically added
020403010400 – ISO/IEC14443B, 106kbps
transmission & reception, Frame Waiting Time
(FWT) of 4.8ms, CRC automatically added
Frame Waiting Time (FWT) definition:
These 2 bytes are optional. The default value
corresponds to a FWT of 4949ms, answer to
ATTRIB.
2 7:0 MM (max 255, i.e. 0xFF)
FWT  ^{2PP  MM1 DD 128 32} [s]
13.56
3 7:0 DD (max 127, i.e. 0x7F)
5:4 15:0 TTTT
6 7:0 YY
7 7:0 ZZ
8
7:0 NEMD
9
7:0 NEMDRES
If PP is defined, MM must be also set, but DD
still remains optional
Timing: TR0 = TTTT/13.56 us
Coded with LSB first,
default value 1023 = 0x3FF
Timing: Min_TR1 = 128 * YY / 13.56us.
Default value: 0
Timing: Max_TR1 = 128 * ZZ / 13.56us.
Default value:26 , i.e. 0x1A
