Thelen Posted March 17, 2002 Author Share Posted March 17, 2002 well i've found the pinout already !!! but now i've got some questions, could somebody explain what the RDY, /RES, oo and o2 lines do ? any help would be great. TheleN Quote Link to comment Share on other sites More sharing options...
DanBoris Posted March 18, 2002 Share Posted March 18, 2002 /RES = Reset. Pulling this low resets the processor. RDY = Ready. When RDY goes low, it essentially stops the execution of instructions by the processor. This is usually used when a device takes longer then usual to read or write data. When the processor attemps to write to a slow device, the device will pull RDY low until it has actually written the data. O0 = Phase 0: This is the master input clock to the processor O2 = Phase 2: This is an output clock from the processor that is derived from Phase 0. It is used to synchronize read and write to external devices. Dan Quote Link to comment Share on other sites More sharing options...
