digital I/O and shared pin functions (continued)
Output Control Registers — used to control the multiplexer selection that chooses between the primary
function of a pin or the general-purpose I/O function.
Data and Control Registers — used to control the data and data direction of bidirectional I/O pins.
description of shared I/O pins
The control structure for shared I/O pins is shown in Figure 18, where each pin has three bits that define its
operation:
MUX control bit — this bit selects between the primary function (1) and I/O function (0) of the pin.
I/O direction bit — if the I/O function is selected for the pin (MUX control bit is set to 0), this bit determines
whether the pin is an input (0) or an output (1).
I/O data bit — if the I/O function is selected for the pin (MUX control bit is set to 0) and the direction selected
is an input, data is read from this bit; if the direction selected is an output, data is written to this bit.
The MUX control bit, I/O direction bit, and I/O data bit are in the I/O control registers.
