Notes:
/ =Two functions available on the pin at the same time. { } = Function during hardware reset. [ ] = Alternative function selected
by firmware configuration. [[ ]] = Alternate function selected by a hardware configuration pin state at power-on reset. This does not
apply to [[BNDSCN_TCK]], [[BNDSCN_TMS]], [[BNDSCN_TDI]], and [[BNDSCN_TDO]]. These functions are enabled by the
BNDSCN_EN signal.
