General-Purpose Input/Output
The Z8 Encore! XP F082A Series products support a maximum of 25 port pins (Ports A–
D) for general-purpose input/output (GPIO) operations. Each port contains control and
data registers. The GPIO control registers determine data direction, open-drain, output
drive current, programmable pull-ups, Stop Mode Recovery functionality and alternate pin
functions. Each port pin is individually programmable. In addition, the Port C pins are
capable of direct LED drive at programmable drive strengths.
