  • Page 26 Register Structure and Format The PCL-812PG requires 16 consecutive addresses in I/O space. The most important issue in programming the PCL-812PG is understanding the meaning of the 16 registers addressable from the selected I/O port base address. A summary map of the functions of each address and the data format of each register are given in the following sections.
  • Page 27 4.7 Mode Control Register The mode control register is a write-only register using address BASE +11. This register provides the way to control the operating modes of the PCL-812PG. Data Format: A. Under internal trigger condition (JP1 is set to internal)
  • Page 28 Data Format: 5.4 Trigger Mode The PCL-812PG A/D conversions can be triggered in any one of three ways - software trigger, on- board programmable pacer or external pulse trigger. The software trigger is controlled by the application program issued software command. Writing to register BASE +12 with any value causes a software trigger.
  • Page 29 The DMA level selection jumper, JP5 and JP6, and the DMA enable bit in the PCL-812PG control register as well as the 8237 DMA controller registers must be set up before performing DMA operations. It is recommended that users use the PCL- 812PG driver to perform DMA operations.
