16-bit output

term_cntrl:

the terminator control

PAOFF_PBOFF: PORTA terminator OFF, PORTB

terminator OFF

PAOFF_PBON: PORTA terminator OFF, PORTB

terminator ON

PAON_PBOFF: PORTA terminator ON, PORTB

terminator OFF

PAON_PBON: PORTA terminator ON, PORTB terminator

ON

(note: term_cntrl is used to control the ON/OFF
of the active terminators, not terminal power
output: TERMPER)

cntrl_pol:

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:

(1) DIREQ

DIREQ_POS: DIREQ signal is rising edge active

DIREQ_NEG:

DIREQ signal is falling edge active

(2) DIACK

DIACK_POS: DIACK signal is rising edge active

DIACK_NEG:

DIACK signal is falling edge active

(3) DITRIG

DITRIG_POS: DITRIG signal is rising edge active

DITRIG_NEG:

DITRIG signal is falling edge active

(4) DOREQ

DOREQ_POS: DOREQ signal is rising edge active

DOREQ_NEG: DOREQ signal is falling edge active
(5) DOACK

DOACK_POS: DOACK signal is rising edge active

DOACK_NEG: DOACK signal is falling edge active
(6) DOTRIG

DOTRIG_POS: DOTRIG signal is rising edge active

DOTRIG_NEG: DOTRIG signal is falling edge active
