Intelligent CAMAC I/O module based on the Signetics 8X300 microcontroller
An intelligent CAMAC I/O module based on the Signetics 8X300 microcontroller was developed. Sixteen 8-bit I/O ports were utilized; eight are dedicated for data transfers with external devices and/or processes, and eight are dedicated to communication with the CAMAC dataway. Separate status and data registers are provided. The input status port (SIN) can receive up to seven individual signals from external devices or the host computer, while the output status port (SOUT) can be used to provide up to seven internally graded LAMs and one bit can be used to generate a Q-response for termination of block transfers. Diagnostic software was developed to operate on the host computer which fully tests all implemented instructions. The device is used in a high-speed memory mapping scheme for data acquisition with a two-dimensional position-sensitive detector system. 8 figures, 3 tables.
