Status Bits
TMC2084 has multiple status bits that indicate its various states and transmits them as a part of the INPUT
DATA packet. Setting anyone of these statuses bits to "1" causes it to keep its value until it is cleared. Any
status bit is cleared when the OUTPUT DATA packet in which its corresponding status bit is set to "1" is
received. Also, they are cleared by the hardware reset and receiving the SOFTWARE RESET command.
RXERR
nNSTCOUT
nTKN2ME
nTXDONE
nRCNERR
Indicates that the device stopped receiving a packet since it detected an error during it
(the packet was discarded).
1: Receiving error is detected
0: Non error
• Dropping from network (MYRECON asserted)
• Expiring idle timer
• Token retry
