Advanced Digital I/O (aDIO™) Port (CN6)
Connector
CN6
is configured as an aDIO port. aDIO is 12 digital bits configured as 8-bit programmable and 4-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
Advanced Digital I/O Ports (aDIO™)
—page 57 for information on programming the aDIO.
