Description
If this bit is set to logic 0, all receiving bits will be cleared after a
collision. This bit shall only be used during bitwise anticollision at
106 kbit, otherwise it shall be set to logic 1.
Reserved for future use.
Set to logic 1, if no Collision is detected or the Position of the
Collision is out of the range of bits CollPos. This bit shall only be
interpreted in Passive Communication mode at 106 kbit or
ISO/IEC 14443A/MIFARE Reader/Writer mode.
These bits show the bit position of the first detected collision in a
received frame, only data bits are interpreted.
Example:
00h
01h
08h
These bits shall only be interpreted in Passive Communication mode
at 106 kbit or ISO/IEC 14443A/MIFARE Reader/Writer mode if bit
CollPosNotValid is set to logic 0.
