Revision 0.2 (10-23-08)
COMR7 Register
Seven registers are defined for COMR7, selected by the selection of the SUBAD [3:0] bits of COMR5.
*1 Not equivalent to the ARCNET original specifications.
(Reduction in a the number of bits)
- When reading/writing: ARCNET Tentative ID register
TID [4:0] (bits 4 to 0)
The ID value specified by this register is compared with the ID value in a token signal in the network and
the results indicated by 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.
