The polarity configuration. This argument is an
integer expression formed from one or more of the
manifest constants defined in 7300.h. There are
six groups of constants:
DIREQ_POS: DIREQ signal is rising edge active
DIREQ_NEG: DIREQ signal is falling edge active
DIACK_POS: DIACK signal is rising edge active
DIACK_NEG: DIACK signal is falling edge active
DITRIG_POS: DITRIG signal is rising edge active
DITRIG_NEG: DITRIG signal is falling edge active
DOREQ_POS: DOREQ signal is rising edge active
DOREQ_NEG: DOREQ signal is falling edge active
DOACK_POS: DOACK signal is rising edge active
DOACK_NEG: DOACK signal is falling edge active
DOTRIG_POS: DOTRIG signal is rising edge active
DOTRIG_NEG: DOTRIG signal is f alling edge active
