1) Every time there is a fault, the fault counter’s value will be incremented by one. The corresponding information will be stored in non-volatile
memory and can be used to analyze how many faults have occurred since the fault buffer was last reset. This makes it possible to compare
it to the information obtained the last time the fault buffer was read in order to determine whether the messages in the fault buffer listed
all faults or whether some have already been lost in the stack. As long as the difference between two read operations on the parameters
is smaller than or equal to 8, all previous faults in the fault buffer will be accessible. The mechanism behind the fault buffer can result in
a second or third fault appearing as a subsequent fault after a first fault: In this case, the user will only receive one single piece of
information with the error bit, although there will actually be three new messages. In these cases, the fault counter can help determine
which fault occurred first. DS7-SWD does not support any subsequent fault analyses.
