The CC121 ARCNET interface is a VMEbus module that allows to interface VMEbus systems to ARCNET token-passing networks. The board, which is based on the SMC COM9026 ARCNET controller, includes a 2-kbyte high-speed dual-ported RAM data buffer. It operates as a VMEbus slave module with 8-bit access to the controller chip and onboard registers, and 8- or 16-bit access to the data buffer. A separate control register allows the user to mask interrupts from the controller, or reset the board. Another register allows the user to read the ARCNET node ID at any time.
