(1) Configurable function through NVM register setting.
(2) PU = Pullup, PD = Pulldown, SPU = Software-configurable pullup, SPD = Software-configurable pulldown.
(3) When VIO is not available, the push-pull pin must be configured as low output to minimize current leakage from the IO cell.
(4) PP = Push-pull, OD = Open-drain.
(5) Deglitch time is only applicable when option is enabled.
(6) NVM-configuration for I2C/SPI and SPMI cannot be overwritten during operation.
