aDIO with Wake-on-aDIO
RTD’s exclusive multiPort™ allows the parallel port to be configured as an Advanced Digital I/O (aDIO™), ECP/
EPP parallel port, or a floppy drive. aDIO™ is 16 digital bits configured as 8 bit-direction programmable and 8-bit
port-direction programmable I/O giving you any combination of inputs and outputs. Match, event, and strobe
interrupt modes mean no more wasting valuable processor time polling digital inputs. Interrupts are generated
when the 8 bit-direction programmable digital inputs match a pattern or on any value change event. Bit masking
allows selecting any subgroup of eight bits. The strobe input latches data into the bit-programmable port and
generates an interrupt. Any of the interrupt modes can be used to generate a wake event from any
standby/powerdown mode.
