Introduction

ADLINK cPCI-8554 series are 12-CH 16-bit timer/counter and digital I/O modules for PXI/CompactPCI form factor. These devices provide ten independent timer/counters and one cascaded 32-bit timer by default, and is configurable to twelve independent timer/counters. The clock source for each timer/counter can be software selected from the cascaded 32-bit timer, external clock source, timer/counter output of the last channel, and the on-board 8 MHz clock. The flexible architecture makes it easy to reconfigure the hardware; for example, up to ten timer/counters can be cascaded to form a 160-bit timer/counter. The hardware can also generate interrupts from either the external interrupt sources or the output of the cascaded 32-bit timer.
