1.3.11 Temporary Data Memory
These data memories are used for temporary storage. When arithmetic instructions
are used, temporary data memories can be used to temporarily store the data for
arithmetic operations as well as the results of arithmetic operations.
Attribute
R: Read
W: Write
*
Both R and W are enabled when special functions are not used.
Note 1: Temporary data memories are initialized when the power is turned on.
Note 2: TM20, TM30, and TM31 are read-only, so cannot be used for writing.
However, TM28 can be used for both reading and writing if special functions are not
used.
Note 3: TM00 and TM01 are used by the MUL and DIV instructions. Never use them
for any other purpose.
