Page 6: Introduction
In t r o d u c t i o n The PCI-1751 is a 48-bit DI/O and counter/timer card with PCI bus. It provides you with 48 bits of parallel digital input/output as well as 3 timers. It emulates mode 0 of the 8255 PPI chip, but the buffered circuits offer a higher driving capability than the 8255. - Page 7 • Interrupt handling • Interrupt output pin for simultaneously triggering external devices with the interrupt • High density SCSI 68-pin connector • Output status readback • Two 16-bit timers can be cascaded to one 32-bit timer, and can generate watchdog timer interrupts •...

Page 10: Initial Inspection
In i t i al In sp ect i o n Before starting to install the PCI-1751, make sure there is no visible damage on the card. We carefully inspected the card both mechani- cally and electrically before shipment. It should be free of marks and in perfect order on receipt. -
Page 11: Jumper Settings
Ju m p e r Se t t i n g s We designed the PCI-1751 with ease-of-use in mind. It is a "plug and play" card, i.e. the system BIOS assigns the system resources such as base address and interrupt automatically. There are only two func- tions with 11 jumpers to be set by the user. - Page 12 Ju m p e r JP4 Re st o r e s Po r t s t o Th e i r Co n d i - t i o n Pr i o r t o Re se t Jumper JP4 gives the PCI-1751 a new and valuable capability. With JP4 enabled, the PCI-1751 "memorizes" all port I/O settings and output values, and, in the event of a "hot"...
- Page 13 Se le c t Clo ck So u r ce o f Ti m e r s an d Co u n t e r Jumpers JP1, JP2 and JP3 are used to select the clock source of Timer 0, Timer 1 and Counter 2, respectively. Short the upper two pins of the jumpers to select an external clock source, or short the lower two pins to select an internal clock source.

Page 21: Timer/Counter Operation
Ti m e r / Co u n t e r Op e r at i o n In t r o d u c t i o n The PCI-1751 includes one 8254 compatible programmable timer/ counter chip which provides three 16-bit counters, designated as Timer 0, Timer1 and Counter 2. - Page 22 Counter 2 is an event counter. Counter 2 is set as mode 0 (interrupt on terminal count) in the driver provided by Advantech. Ti m e r / Co u n t e r Fr e q u e n c y a n d In t e r r u p t The input clock frequency of the counter/timers is 10 MHz.

Page 23: Interrupt Function
Two lines in each I/O port (C0 and C4) and two of the three counter outputs (Timer 1 and Counter 2) are connected to the interrupt circuitry. The "Interrupt Control Register" of the PCI-1751 controls how the combination of the 6 signals generates an interrupt. Two interrupt request signals can be generated at the same time, and then the software can service these two request signals by ISR. - Page 24 1, as indicated in Figure 3-3. Table 3-3 shows the relationship between an interrupt source and the values in the mode bits.

- Page 33 Co u n t e r Op e r at i o n s Re a d / W r i t e Op e r a t i o n Before you write the initial count to each counter, you must first specify the read/write operation type, operating mode and counter type in the control byte and write the control byte to the control register (BASE+27).
- Page 34 Co u n t e r Ap p l i cat i o n s The 8254 compatible programmable interval timer/counter on your PCI-1751 interface card is a a very useful device. You can program timers 1 and 2 to serve as timers, event counters, square wave genera- tors, or as a watchdog to generate regular interrupts at a fixed interval.
