4K 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.
