I/O ports
Introduction
The I/O ports offer different functional modes:
●
●
●
●
An I/O port consists of up to 8 pins. Each pin can be programmed independently as a digital
input (with or without interrupt generation) or a digital output.
Functional description
Each port is associated to 2 main registers:
●
●
Each I/O pin may be programmed using the corresponding register bits in DDR register: bit
X corresponding to pin X of the port. The same correspondence is used for the DR register.
Table 10.
Input modes
The input configuration is selected by clearing the corresponding DDR register bit.
In this case, reading the DR register returns the digital value applied to the external I/O pin.
All the inputs are triggered by a Schmitt trigger.
When switching from input mode to output mode, the DR register should be written first to
output the correct value as soon as the port is configured as an output.
Interrupt function
When an I/O is configured as an input with interrupt, an event on this I/O can generate an
external interrupt request to the CPU. The interrupt sensitivity is given independently
according to the description mentioned in the ITRFRE interrupt register.
Each pin can independently generate an interrupt request.
Each external interrupt vector is linked to a dedicated group of I/O port pins (see interrupts
section). If more than one input pin is selected simultaneously as an interrupt source, this is
logically ORed. For this reason if one of the interrupt pins is tied low, the other ones are
masked.
