pinmux_spim0_usefpga
Selection between HPS Pin and FPGA Interface for SPIM0 signals
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.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
