The Z8 Encore! F083A Series products support a maximum of 23 port pins (Port 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.
Figure 8
the ability to accommodate alternate function and variable port current drive strength is
not displayed.
