Selection between GPIO and LoanIO output and output enable for GPIO44 and LoanIO44. These signals
drive the Pin Mux. The Pin Mux must be configured to use GPIO/LoanIO in addition to these settings
Only reset by a cold reset (ignores warm reset). NOTE: These registers should not be modified after IO
configuration.There is no support for dynamically changing the Pin Mux selections.
