4 ON-CHIP PERIPHERALS
4.1 I/O PORTS
4.1.1 Introduction
The I/O ports allow the transfer of data through
digital inputs and outputs, and, for specific pins,
the input of analog signals or the Input/Output of
alternate signals for on-chip peripherals (DDC,
TIMER...).
Each pin can be programmed independently as
digital input or digital output. Each pin can be an
analog input when an analog switch is connected
to the Analog to Digital Converter (ADC).
Figure 15. I/O Pin Typical Circuit
Note: This is the typical I/O pin configuration. For cost optimization, each port is customized with a specific configuration.
