The probing of an SX-A or eX device may require special setup
because it Actel recommends that you use a series 70 ohm termination
on all the probe connectors (TDI, TDO, TCK, TMS, PRA, PRB). The 70
ohm series termination is used to prevent data transmission corruption
during probing and reading checksum.
