Table The card is designed to use the PPI in Mode 0 wherein: Any port can be configured as an input or an output. Other than Acces PCI-DIO-24S above, no other warranty, expressed or implied, shall apply to any and all such equipment furnished or sold by Portwell. Block Diagram Option Selection Option Selection Map Address Selection Address Assignment Table Control Register Bit Assignment Change-of-state-interrupt-enable Register Connector Pin Assignments They can be programmed to accept inputs or to provide outputs on two groups of three 8-bit ports.

Further, in each group, one of the ports can be Acces PCI-DIO-24S divided into two four-bit nibbles. The feature that distinguishes the "48S" model from the "48" card is that the state of all inputs can be monitored and, if any one or more bits change state, a latched interrupt request can be generated. Thus, it is not necessary to use software to continuously poll the inputs Acces PCI-DIO-24S detect a change of state. Six bits in that register each control an eight-input port at one of two type Programmable Peripheral Interface chips. The change-of-state interrupt latch can be cleared by a software write.

Also, bit C3 at each bit port can be used as an external interrupt to the computer if the IEN jumpers are installed. These cards use one address space, and occupy 16 consecutive register locations.
