Table 68. Description of FelNFC1Reg bits
Bit Symbol Description
7 to 6 FelSyncLen Defines the length of the Sync bytes.
Value Sync- bytes in hex
00 B2 4D
01 00 B2 4D
10 00 00 B2 4D
11 00 00 00 B2 4D
5 to 0 DataLenMin These bits define the minimum length of the accepted packet length:
DataLenMin * 4  data packet length
This parameter is ignored at 106 kbit if the bit DetectSync in register
ModeReg is set to logic 0. If a received data packet is shorter than the
defined DataLenMin value, the data packet will be ignored.
