Register : sdmmc_clk_in Mux Selection Register - FLASHIO8

Description

This register is used to control the peripherals connected to sdmmc_clk_in

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.

Data Structure Documentation

struct ALT_SYSMGR_PINMUX_FLSHIO8_s

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
