30<P>This function sets the Data TCM parameter. This parameter contains the Data TCM base address and the effective area size. The base address can be set in units of 16 KB.</P>
31<P>The following sizes can be specified. Specify the logical sum (bitwise OR) of one of these values and the base address as <B><I>param</I></B>. Note that the data TCM built into NITRO and TWL is 16 KB, so only specifications of 16 KB or less are valid.</P>
