1. This pin is tri-stated during reset and then sampled at the end of the reset to determine whether the OS-Link is active and
to determine the function of the shared CPUAnalyse / TrigIn and the ErrorOut / TrigOut, as described in the System
Services chapter. If the ErrorOut pin is sampled high (i.e at VDD) then the DCU signals (TrigIn and TrigOut) are selected
and a low value indicates OS-Link signals (i.e. CPUAnalyse, ErrorOut) are to be used. External 10KΩ pull-up or pull-
down resistors should be fitted to the ErrorOut according to the functionality desired.
