/* Pin modes
* =========
* The EPUN and EPD bits in the SFS registers allow the selection of weak on-chip
* pull-up or pull-down resistors with a typical value of 50 kOhm for each pin or the
* selection of the repeater mode.
* The possible on-chip resistor configurations are pull-up enabled, pull-down enabled, or no
* pull-up/pull-down. The default value is pull-up enabled.
*
* The repeater mode enables the pull-up resistor if the pin is at a logic HIGH and enables
* the pull-down resistor if the pin is at a logic LOW. This causes the pin to retain its last
* known state if it is configured as an input and is not driven externally. Repeater mode may
* typically be used to prevent a pin from floating (and potentially using significant power if it
* floats to an indeterminate state) if it is temporarily not driven.
* Repeater mode is enabled when both pull-up and pull-down are enabled.
*
* To be able to receive a digital signal, the input buffer must be enabled through bit EZI in
* the pin configuration registers. By default, the input buffer is disabled.
* For pads that support both a digital and an analog function, the input buffer must be
* disabled before enabling the analog function.
*
* All digital pins support a programmable glitch filter (bit ZIF), which can be switched on or
* off. By default, the glitch filter is on. The glitch filter should be disabled for
* clocking signals with frequencies higher than 30 MHz.
*
* Normal-drive and high-speed pins support a programmable slew rate (bit EHS) to select
* between lower noise and low speed or higher noise and high speed . The typical
* frequencies supported are 50 MHz/80 MHz for normal-drive pins and 75 MHz/180 MHz for
* high-speed pins.
