9. I/O Port
The eight I/O pins (six on 8-pin package option) are bi-
directional (see Figure 28). The bi-directional I/O pins can be
individually con
fi
gured by software to operate as high-
impedance inputs, as inputs with weak pull-up, or as push-pull
outputs. The operating state is determined by the contents of
the corresponding bits in the data and con
fi
guration registers.
Each bi-directional I/O pin can be used for general purpose I/O,
or in some cases, for a speci
fi
c alternate function determined by
the on-chip hardware.
Figure 28. PORTGD Logic Diagram
9.1 I/O registers
The I/O pins (G0-G7) have three memory-mapped port regis-
ters associated with the I/O circuitry: a port con
fi
guration regis-
ter (PORTGC), a port data register (PORTGD), and a port input
register (PORTGP). PORTGC is used to con
fi
gure the pins as
inputs or outputs. A pin may be con
fi
gured as an input by writing
a 0 or as an output by writing a 1 to its corresponding PORTGC
bit. If a pin is con
fi
gured as an output, its PORTGD bit repre-
sents the state of the pin (1 = logic high, 0 = logic low). If the pin
is con
fi
gured as an input, its PORTGD bit selects whether the
pin is a weak pull-up or a high-impedance input. Table 13 pro-
vides details of the port con
fi
guration options. The port con
fi
gu-
ration and data registers can both be read from or written to.
Reading PORTGP returns the value of the port pins regardless
of how the pins are con
fi
gured. Since this device supports MIW,
PORTG inputs have Schmitt triggers.
