Страница 5: ...Contact us for details The STEbus interface is an important feature of the SC88T The bus is being ratified by the IEEE IEEE designation is P1000 and it is designed as a processor and manufacturer independent asynchronous multiprocessing bus The asynchronous nature of the bus means that a slave board memory or I O must acknowledge commands by the SC88T which will wait until it does so that any spee...

Страница 8: ...robes A SC88T configured as standard will generate all necessary bus signals All that is required to generate a bus access is that you try to read from or write to a memory or I O location which the on board logic defines as on the bus See the Memory Map and I O Devices sections for details on which addresses are on board and which are not Note The internal timers on the SC88T can be programmed so...
