This escape command can be used to restrict the baud rate for contactless cards to certain values. The
input buffer is
Byte #

DR=2 supported, if bit is set to 1
DR=4 supported, if bit is set to 1
DR=8 supported, if bit is set to 1
shall be set to 0, 1 is RFU
DS=2 supported, if bit is set to 1
DS=4 supported, if bit is set to 1
DS=8 supported, if bit is set to 1
1 if the same D is required for both
communication directions
0 if different D is supported for ach
communication direction
Encoding of the baud rate to be allowed if
B1 value is 0x01. No need to send this byte
in case B1 has the value =x00
NULL
If B1=0x00
The output buffer is
