9.4.3.1 Control Register
Any bit set to
0
in the Control Register sets the corresponding Port pin to MCU I/O Mode,
and a
1
sets it to Address Out Mode. The default mode is MCU I/O. Only Ports A and B
have an associated Control Register.
9.4.3.2 Direction Register
The Direction Register, in conjunction with the output enable (except for Port D), controls
the direction of data flow in the I/O Ports. Any bit set to
1
in the Direction Register will
cause the corresponding pin to be an output, and any bit set to
0
will cause it to be an
input. The default mode for all port pins is input.
Figures 26 and 28 show the Port Architecture diagrams for Ports A/B and C, respectively.
The direction of data flow for Ports A, B, and C are controlled not only by the direction
register, but also by the output enable product term from the PLD AND array. If the output
enable product term is not active, the Direction Register has sole control of a given pin
s
direction.
An example of a configuration for a port with the three least significant bits set to output and
the remainder set to input is shown in Table 26. Since Port D only contains three pins, the
Direction Register for Port D has only the three least significant bits active.
