Revision 0.1 (06-07-07)
MAXID 4-0 (bits 4 to 0)
These bits specify the max. node ID.
When INIMODE in the mode register and nDIAG pin are set to 1, the value set in this register is selected
as the max. node ID. When INIMODE is set to 0, values in MAXID 4-0 of the external input pin become
readable. Refer to section 1.5.9 - MAXID Number Setup.
To change these bits, be sure to set TXEN to 0 (off-line) beforehand. If these bits change during the on-
line state, it executes a software reset automatically. (The software reset is released automatically.)
NID4-0 (bits 4 to 0)
These bits specify the node ID.
When INIMODE of the Mode register is set to 1, the value set in this register is selected as the node ID.
When INIMODE is set to 0, values in NID 4-0 of the external input pin become readable. Refer to section
1.5.10 - Node ID Setup.
To change these bits, be sure to set TXEN to 0 (off-line) beforehand. If these bits change during the on-
line state, it executes a software reset automatically (the software reset is released automatically).
PS1-0 (bits 1 to 0)
These bits specify the page size.
When INIMODE of the mode register is set to 1, the value set in this register is selected as the page size.
When INIMODE is set to 0, values in PS1-0 of the external input pin become readable. Refer to section
1.5.8 - Page Size Selection.
