General-Purpose I/O
The Z8FMC16100 Series Flash MCU contains general-purpose input/output pins (GPIO)
arranged as Ports A–C. Each port contains control and data registers. The GPIO control
registers are used to determine data direction, open-drain, output drive current, pull-up,
and alternate pin functions. Each port pin is individually programmable.
