Introduction 1 ® This manual describes the IQ80960RM and IQ80960RN evaluation platforms for Intel’s i960 RM/RN I/O processor. The i960 RM/RN I/O processors combine an 80960JT core with two PCI bus interfaces, as well as a memory controller, DMA channels, an interrupt controller interface, and 2 an I C serial bus. The difference between the two processors is that the 80960RN utilizes 64-bit primary PCI and secondary PCI buses while the 80960RM utilizes both a 32-bit primary and secondary PCI

Introduction 1.7 Notational-Conventions The following notation conventions are consistent with other i960 RM/RN I/O processor documentation and general industry standards. # or overbar In code examples the pound symbol (#) is appended to a signal name to indicate that the signal is active. Normally inverted clock signals are indicated with an overbar above the signal name (e.g., RAS). Bold Indicates user entry and/or commands. PLD signal names are in bold lowercase letters (e.g., h_off, h_on)
