General Purpose Input/Output
The Z8 Encore! F0830 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.
