Write used in the flag clearing mechanism. Writing a one to the flag clears the flag. Writing a zero will not
affect the current status of the bit.
All bits reset to zero.
TFLG2 indicates when interrupt conditions have occurred. The flag can be cleared via the normal flag
clearing mechanism (writing a one to the flag) or via the fast flag clearing mechanism (Reference TFFCA
