Revision 0.1 (06-07-07)
EXCNAK (bit 3)
When this bit is 1, it indicates that a “NAK” was received 4 or 128 times from the receiving node (Four
NAKS is determined by bit a setting) in response to “Free Buffer Enquiry” during the send. It is possibly
caused by the blind state (ECRI = 1) of the destination node. This bit can not be cleared by bit-read but
can be cleared by software reset or by the writing of the EXCNAK clear command (0Eh).
TENTID (bit 2)
When this bit is 1, it indicates that COMR7-000: Tentative ID register matches the ID value in a token
signal in the network. Note that the ID value in a token signal sent by this bit itself cannot be compared.
With the function in normal online state (TXEN = 1), a node ID map of the network can be created. This bit
is cleared by software reset or by being read.
NXTIDERR (bit 1)
This bit is set when receiving no response from the token passed, to. the node with the ID of node ID + 1
and the token is passed to another node. This bit can be cleared by a software reset or by the writing of
NXTIDERR clear command (09h), but is not cleared with read out.
*2: Node 01 when the node is MAXID node.
To detect the DUPID and TENTID bits, wait for the maximum polling cycle time of token after the NID or
TENTID value is changed.
- When writing: ARCNET command register
This command register is not used in CircLink; the EC command register in 3.2.12 must be used. The
commands described there include all valid CircLink commands.
