PRODUCTION DATA
SDFM operation with qualified GPIO (3-sample window) is defined by setting GPyQSELn = 0b01. When using this qualified GPIO (3-sample window) mode, the timing requirement for the tw(GPI) pulse duration of 2tc(SYSCLK) must be met. It is important for both SD-Cx and SD-Dx pairs to be configured with the same GPIO qualification option. Section 6.11.5.2.1 lists the SDFM timing requirements when using the GPIO input qualification (3-sample window) option. Figure 6-57 through Figure 6-60 show the SDFM timing diagrams.
