Pin Mux Control Group Register Descriptions
GPLMUX12
Selection between GPIO and LoanIO output and output enable for GPIO12 and LoanIO12. 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.
