digital I/O and shared pin functions
The 240xA has up to 41 general-purpose, bidirectional, digital I/O (GPIO) pins
—
most of which are shared
between primary functions and I/O. Most I/O pins of the 240xA are shared with other functions. The digital I/O
ports module provides a flexible method for controlling both dedicated I/O and shared pin functions. All I/O and
shared pin functions are controlled using eight 16-bit registers. These registers are divided into two types:
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 17, 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.
