Each I/O line is designed with an embedded pull-up resistor. The internal pull-ups have a typical
value of 200 kOhm (see the product electrical characteristics for more details about this value).
The pull-up resistor can be enabled or disabled by writing respectively PIO_PUER (Pull-up
Enable Register) and PIO_PUDR (Pull-up Disable Resistor). Writing in these registers results in
setting or clearing the corresponding bit in PIO_PUSR (Pull-up Status Register). Reading a 1 in
PIO_PUSR means the pull-up is disabled and reading a 0 means the pull-up is enabled.
Control of the pull-up resistor is possible regardless of the configuration of the I/O line.
