CROSSPOINT: A single cell controlled by two RAM bits. The RAM bits are connected in a master-slave
configuration to provide an update for programming and changing program information all at once.
CROSSPOINT ARRAY: An array of Crosspoint cells used to connect any input port to any output port.
INPUT OR OUTPUT PATH: The signal flow from pin to array and array to pin. Each path has a register with
selectable clocks, drivers for the loaded outputs with selectable enables, and sense circuits to detect changes on
either side of the IO Buffer.
PORT: A name followed by a number to identify a pin on the device.
RAPIDCONFIGURE: A parallel programming method for the OCX devices. The RC mode uses 23 dedicated
pins to program the Crosspoint Array and the IO Buffers. The 23 pins consist of an enable, a clock, four
instruction bits, two seven-bit address fields, and a three-bit data field.
