Implementation, Diagnostics

Some of the tests require changes due to the new hardware

Read/write test for DSP code loading memory

Flash manager must do this

It is not possible to set loops in ET units as the TCSM3i units may not have control over their ET units

Loop in the submultiplexer part

External clocks must be tested

Clock units can perform their own diagnostics

Flash test calculates checksums from code memory

Changed to calculate checksum from storage flash as well
