digital I/O and shared pin functions
The ’F243 has a total of 32 general-purpose, bidirectional, digital I/O (GPIO) pins that function as follows: six
pins are dedicated I/O pins (see Table 7) and 26 pins are shared between primary functions and I/O. The ’F241
has 26 I/O pins; all 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 4, 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.
