Packages
The Z8F640x family products support a maximum of seven 8-bit ports (Ports A-G) and
one 4-bit port (Port H) for general-purpose input/output (I/O) operations. Each port con-
tains control and data registers. The GPIO control registers are used to determine data
direction, open-drain, output drive current and alternate pin functions. Each port pin is
individually programmable.
Not all Z8F640x family products support all 8 ports (A-H). Table 10 lists the port pins
available with each device and package type.
