param | Data TCM parameter |
None.
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.
The following sizes can be specified. Use the logical OR of this value and the base address for the parameter param
. Note that the data TCM inside NITRO is 16 KB, so it is valid only when less than 16 KB is specified
