Advanced Digital I/O (aDIO) Port (CN6)<br />
CN6 is configured as an aDIO port. aDIO is 12 digital bits configured as 8-bit programmable and 4-bit port<br />
programmable I/O, providing any combination of inputs and outputs. Match, event, and strobe interrupt modes<br />
mean no more wasting valuable processor time polling digital inputs. Interrupts are generated when the 8-bit<br />
programmable digital inputs match a pattern, or on any value change event. Bit masking allows selecting any<br />
subgroup of 8 bits. The strobe input latches data into the bit programmable port and generates an interrupt.<br />
Refer to Advanced Digital I/O Ports (aDIO)—page 60 for information on programming the aDIO.<br />
