Settings:Pin Configuration[MFP20_SEL0][MFP20_SEL1][MFP20_SEL2] = 011 or 1xx are unused settings and cause the pin to be configured as input in HIGH-Z state.
All three RLX pins must be selected together as (1) LED pins or (2) GPIO or (3) GPIO+PDSG. It is not possible for a subset of the pins to be used for a LED drive (in charlieplexing mode) and the remainder to be used as GPIO. However, if they are used as GPIO, it is possible for a subset of the pins to be configured as inputs, while the remaining pins are configured as outputs. It is also possible for a pin to be configured as GPIO and used to power an LED (just not using charlieplexing). The LED support is expanded to allow up to six LEDs.
