PIO-D96 Series Card96-channel DIO BoardUser Manual, Ver. 2.3, Jun. 2018, PMH-008-23 Page: 436.3.5 Aux Status Register(Read/Write): wBase+7Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0Aux7 Aux6 Aux5 Aux4 Aux3 Aux2 Aux1 Aux0Aux0=P2C0, Aux1=P5C0, Aux2=P8C0, Aux3=P11C0, Aux7~4=Aux-ID. Refer to DEMO5.C for moreinformation. The Aux 0~3 are used as interrupt source. The interrupt service routine has to read thisregister to identify the interrupt source. Refer to Section 2.7 “Interrupt Operation” for moreinformation.6.3.6 Interrupt Polarity Register(Read/Write): wBase+0x2ABit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 00 0 0 0 INV3 INV2 INV1 INV0This register provides a function to control invert or non-invert for the interrupt signal source. Adetailed application example is given below.INV0=1 select the non-inverted signal from P2C0INV0=0 select the inverted signal from P2C0For example:outportb(wBase+0x2a,0x0f); /* select the non-inverted input P2/5/8/11C0 */outportb(wBase+0x2a,0x00); /* select the inverted input of P2/5/8/11C0 */outportb(wBase+0x2a,0x0e); /* select the inverted input of P2C0 *//* select the non-inverted input P5/8/11C0 */outportb(wBase+0x2a,0x0c); /* select the inverted input of P2/5C0 *//* select the non-inverted input P8/11C0 */Refer to Section 2.7 “Interrupt Operation” and DEMO5.C (DOS) for more information.
