IBM CMX58886CX MultiPort CN6, MultiPort Configured as an Advanced Digital I/O aDIO Port

multiPort™ (CN6)

RTD’s exclusive multiPort can be configured as an Advanced Digital I/O (aDIO™), a parallel port, or a floppy drive. Refer to Chapter 4, Using the cpuModule, to configure the multiPort.

multiPort Configured as an Advanced Digital I/O (aDIO™) Port

The mulitPort connector (CN6) can be configured as an aDIO port. aDIO is 16 digital bits configured as 8-bit programmable and 8-bit port programmable I/O, providing 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 programmable digital inputs match a pattern, or on any value change event. Bit masking allows selecting any subgroup of 8 bits. The strobe input latches data into the bit programmable port and generates an interrupt. Refer to multiPort: Advanced Digital I/O Ports (aDIO™) on page 56 for information on programming the multiPort.
