When using this synchronized GPIO mode, the timing requirement for 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 SYNC option. This section lists the SDFM timing requirements when using the synchronized GPIO (SYNC) option. Figure 6-73 shows the SDFM timing diagram.
The SDFM Timing Requirements When Using Synchronized GPIO - SYNC Option table lists the SDFM timing requirements. The following configurations should be made:
The SDFM Synchronized GPIO (SYNC) option provides protection against SDFM module corruption due to occasional random noise glitches on the SDx_Cy pin that may result in a false comparator trip and filter output.
The SDFM Synchronized GPIO (SYNC) mode does not provide protection against persistent violations of the above timing requirements. Timing violations will result in data corruption proportional to the number of bits which violate the requirements.
