5.13 _8554_Set_INT_Control

@ Description

The PCI-8554 has dual interrupts system. Two interrupt sources can
be generated and be checked by the software. This function is used
to select and control PCI-8554 interrupt sources. The interrupt
source can be set as from counter #12 output COUT12 (INT1) or
external interrupt signal EXTINT (INT2).

@ Syntax

C/C++ (DOS)

U16 _8554_Set_INT_Control (U16 cardNo, U16 int1Flag, U16

int2Flag)

C/C++ (Windows 95)

U16 W_8554_Set_INT_Control (U16 cardNo, U16 int1Flag, U16

int2Flag)

Visual Basic (Windows 95)

W_8554_Set_INT_Control (ByVal cardNo As Integer, ByVal

int1Falg As Integer, ByVal int2Falg As Integer)

@ Arguments

cardNo:

card number to select board

int1Flag:

INT1 setting; 0: disable, 1: enable

int2Flag:

INT2 setting; 0: disable, 1: enable
