Using the I/O Pin
Figure 13-1. General I/O pin functionality.
Use of an I/O pin is controlled from the user software. Each port has one Data Direction (DIR),
Data Output Value (OUT) that is used for port pin control. The Data Input Value (IN) register is
used for reading the port pins. In addition each pin has a Pin Configuration (PINnCTRL) register
for additional pin configuration.
Direction of the pin is decided by the DIRn bit in the DIR register. If DIRn is written to one, pin n
is configured as an output pin. If DIRn is written to zero, pin n is configured as an input pin.
When direction is set as output, the OUTn bit in OUT is used to set the value of the pin. If OUTn
is written to one, pin n is driven high. If OUTn is written to zero, pin n is driven low.
The IN register is used for reading the pin value. The pin value can always be read regardless of
the pin being configured as input or output, except if digital input is disabled.
I/O pins are tri-stated when reset condition becomes active, even if no clocks are running.
