To all our customers
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.)
www.DataSheAet4cUc.coormdingly, 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.

How to Use This Manual
This user's manual is written for the M30218 group.
The reader of this manual is expected to have the basic knowledge of electric and logic
circuits and microcomputers.
This manual is for the use of the models below.
• M30217MA-AXXXFP
www.DataSheet4UM.co3m0218MC-AXXXFP
• M30218FCFP
These products have similar features except for the memories, which differ from one product to
another. This manual gives descriptions of M30218MC-AXXXFP. Memories built-in are as shown
below. Be careful when writing a program, as the memories have different capacities.

Bit attribute
Bit symbol
Bit name
TA0OS Timer A0 one-shot start flag
TA1OS Timer A1 one-shot start flag
Function
1: Timer start
When read, the value is 0
RW
TA2OS Timer A2 one-shot start flag
TA3OS Timer A3 one-shot start flag
TA4OS Timer A4 one-shot start flag
Nothing is assigned. In an attempt to write to these bits, write 0. The value, if
read, turns out to be indeterminate.
TA0TGL
TA0TGH
Timer A0 event/trigger
select bit
b7 b6
0 0 : Input on TA0IN is selected (Note)
0 1 : TB2 overflow is selected
1 0 : TA4 overflow is selected
1 1 : TA1 overflow is selected
Note: Set the corresponding port direction register to 0.
When TAiIN is selected, TAiOUT assigned on same pin can not be used. (i=0 to 4)
