Rev. 1.1.0.2
Each I/O line of the GPIO features:
•
•
•
•
•
•
The General Purpose Input/Output manages the I/O pins of the microcontroller. Each I/O line
may be dedicated as a general-purpose I/O or be assigned to a function of an embedded periph-
eral. This assures effective optimization of the pins of a product.
Table 22-1.
Most of the features of the GPIO are configurable for each product. The programmer must refer
to the Peripherals Section for these settings.
Product specific settings includes:
Configurable pin-change, rising-edge or falling-edge interrupt on any I/O line.
A glitch filter providing rejection of pulses shorter than one clock cycle.
Open Drain mode enabling sharing of an I/O line between the MCU and external components.
Input visibility and output control.
Multiplexing of up to four peripheral functions per I/O line.
Programmable internal pull-up resistor.
