Revision 0.1 (06-07-07)
The ID value specified by this register is compared with the ID value in a token signal in the network and
the results reflected in the TENTID bit of the diagnostic register. TENTID becomes 1 if the comparison
result matches.
*1 Not equivalent to the ARCNET original specifications.
(Reduction the number of bits)
- When reading/writing: ARCNET Node ID register
NID [4:0] (bits 4 to 0)
When INIMODE = 1, this bit specifies the node ID. This function is the same as that of the NID register
described in 3.2.23 which is usually used instead of this register.
*1: Not equivalent to the ARCNET original specifications. (Function elimination)
- When reading/writing: ARCNET SETUP1 register
FOURNAKS (bit 6)
This bit specifies the number of NAK responses to the "Free Buffer Enquiry", function of the EXCNAK bit of
the diagnostic register. Setting 1 to this bit specifies 4 times, and to 0 specifies 128 times.
CKP [2:0] (bits 3 to 1)
INIMODE = 1 specifies the communication speed (transfer rate). This function is the same as that of the
CKP register described in 3.2.25 which is usually used instead of this register.
