MODEn determines which mode the pin is in at a given time. Setting MODEn to 0b0000 disables the
pin, reducing power consumption to a minimum. When the output driver is disabled, the pin can be used
as a connection for an analog module (e.g. ADC, LCD...). Input is enabled by setting MODEn to any
value other than 0b0000. The pull-up, pull-down and filter function can optionally be applied to the input,
see Figure 28.2 (p. 392) .
The internal pull-up resistance, R
When the filter is enabled it suppresses glitches with pulse widths as defined by the parameter t
in the device datasheet.
Figure 28.2. Tristated Output with Optional Pull-up or Pull-down
When MODEn=0b0100 or MODEn=0b0101, the pin operates in push-pull mode. In this mode, the pin
is driven either high or low, dependent on the value of GPIO_Px_DOUT. The push-pull configuration is
shown in Figure 28.3 (p. 393) .
