Regarding the change of names mentioned in the document, such as Mitsubishi
Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi
Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names
have in fact all been changed to Renesas Technology Corp. Thank you for your understanding.
Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been
made to the contents of the document, and these changes do not constitute any alteration to the
contents of the document itself.
Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices
and power devices.

Terms to use here are explained as follows.
Nothing is assigned
Nothing is assigned to the bit concerned. When write, set "0" for new function in
future plan.
Must not be set
Not select. The operation at having selected is not guaranteed.
Reserved bit
Reserved bit. Set the specified value.
Function varies with each operation mode
Bit function changes according to the mode of peripheral functions.
Invalid in A mode
The bit concerned has no function in A mode. Set the specified value.
Valid when bit A="0"
When bit A is "1", the bit concerned has no function. When bit A is "0", the bit
concerned has function.
