3.2.2.8  The General Control Register 

 
The general control register (18h) is used to control the add-on interrupt 

source and the A/D trigger method. The format of this register is: 

 

Bit4-2 Bit 

1-0 

Interrupt source 

selection register 

A/D trigger method 

selection register 

 

 

There are four interrupt sources selectable for the OME-PCI-1002 (see 

section 1.4.4).  

 

[Bit4,Bit3,Bit2] Description 

[ 0, 0, 0 ] 

 No interrupt source, disable all interrupts. 

[ 0, 0, 1 ] 

 Interrupt after A/D conversion completes. 

[ 0, 1, 0 ] 

 Interrupt after 8254 timer 0 falling. 

[ 0, 1, 1 ] 

 Interrupt after external trigger falling. 

[ 1, 0, 0 ] 

 Interrupt after 8254 timer 1 falling. 

Others 

 No interrupt source, disable all interrupts. 

 

Note: Bit 3-3 of general control register is set to 0 after a hardware reset.
