CHAPTER 1 INSTALLATION Before installing this card carefully read the Address Selection and Option Selection sections of this manual and configure the card according to your requirements. Be especially careful with address selection. If the addresses of two installed functions overlap, you will experience unpredictable computer behavior. - Page 9 PB751-AT MANUAL INSTALLATION This page intentionally left blank.

Page 10: Functional Description
CHAPTER 2 FUNCTIONAL DESCRIPTION Prototype card PB751-AT provides means for development of custom cards for use in IBM PC/XT and PC/AT or compatible computers. The card buffers all address lines, data lines, and some of the control signals. It also provides address decoding for I/O addresses 000 through 3FF hex and for memory addresses 00000 through FF000 and, allows setup of the selected address block size. -

This line is used to latch valid addresses and memory decodes from the microprocessor. It's available to the I/O channel as an indicator of a valid microprocessor or DMA address (when used with AEN). Microprocessor addresses SA0 through SA19 are latched with the falling edge of BALE.

DMA cycle is reached. I/O ADDRESS MAP The PB751-AT card address can be selected anywhere within the I/O address range 000-3FF hex or the Memory address range 00000-FF000 providing that the address does not over lap that of other installed functions. It is intended that I/O base addresses be selected at four-byte intervals and that memory base address be selected at 4096 byte intervals. - Page 14 PB751-AT MANUAL FUNCTIONAL DESCRIPTION TABLE 1.

CHAPTER 3 ADDRESS SELECTION The PB751-AT card address is set by DIP switch SW1. That switch controls I/O address bits A2 through A9 if jumpers are installed between pins 1 and 2 of W1, W2, W3, W4, W5, W6, W7, and W8. - Page 17 PB751-AT MANUAL ADDRESS SELECTION This page intentionally left blank.

Page 18: Option Selection
Block of Addresses Reserved The size of a block of addresses reserved for the PB751-AT card is selected by the combination of DIP switch settings just mentioned and jumpers marked 8, 16, 32, 32K, 64K, 128K, and 256K. - Page 19 PB751-AT MANUAL OPTION SELECTION As described in the previous section of this manual, DIP switches A2 through A9 are used to set the base address. The A2 position corresponds to the least significant bit of the address in hexadecimal code and the A9 position corresponds to the most significant bit. If a block size of four bytes is selected for an I/O card application (or 2K bytes for memory operation), then all eight switches are available to set the base address.
