9.6.2.6 Default TCK frequency

When the PDB/STAPL file or Chain does not exist, the default TCK frequency is set to 4MHz. In the Single Device File Programming mode, FlashPro® will parse through the file and search for the "freq" keyword and the "MAX_FREQ" Note field, which are expected in all Actel Flash device files. The FlashPro® software uses the lesser value of the two as the default TCK frequency.

In Chain Programming mode, when more than one Actel flash device is targeted in the chain, the FlashPro software passes through all of the files and searches for the "freq" keyword and the "MAX_FREQ" Note field. The FlashPro software uses the lesser value of all the TCK frequency settings and the "MAX_FREQ" Note field values.
