The card emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. The 72 I/O lines are divided into twelve 8-bit I/O ports: A0, B0, C0, A1, B1, C1, A2, B2, C2, A3, B3 and C3. Users can configure each port as input or output via software. 8 eConnectivity Easy to Install: Plug and Play The MIC-3753 uses a PCI controller to interface the card to the PCI bus. The controller fully implements the PCI bus specification Rev 2.1. All bus relative configurations, such as the base address and interrupt assignments, are automatically controlled by software. 9 ICOM Dry Contact Support for Digital Input Each digital input channel of the MIC-3753 accepts either 0 ~ 5 V wet contact or dry contact inputs. This dry contact capability allows the channels to respond to changes in external DC 10 circuitry (e.g., the closing of a switch in the external circuitry) when no voltage is present in the external circuit. Software Reset Protection Fulfills the True Requirement of Industrial Applications When the system is hot reset (the power is not turned off), the MIC-3753 can either retain the value of the last I/O port settings and outputs, or return to its default configuration, 11 UNO-2000/3000 depending on the jumper setting. This function protects the system from wrong operations during unexpected system resets. Interrupt Functions Ensure Faster System Response 12 Two lines of each port C (i.e., ports C0, C1, C2 and C3) are connected to an interrupt circuit. The “Interrupt Control Register” of the MIC-3753 controls how these signals generate VBOX an interrupt. Two interrupt request signals can be generated at the same time, and the software can process these two request signals by ISR. The dual interrupt sources provide the card with more capability and flexibility. 13 The MIC-3753 also provides a “Pattern Match” interrupt function for port A0. The card monitors the states of port A0 and compares them with a pre-set pattern. When the received ADAM-4000 state matches the pre-set pattern, the MIC-3753 generates an interrupt signal to the system. A “Change of State” interrupt function is provided at port B0. When any signal line of port B0 changes its state, the card generates an interrupt to the system to handle this event. 14 These interrupt functions release the CPU from the burden of pulling all I/O points, enabling a PC to handle more I/O points with higher performance.
