SD Card Interface (J7)
The THDB-SUM board has an SD card socket that can be accessed as an optional
external memory in both SPI and 1-bit SD mode.
Figure 2–14 shows the pin-outs of
the SD card socket. Table 2–14 lists the detailed pin mapping between the SD card
socket and the HSMC connector.
Table 2–15 lists the SD card socket board reference and manufacturing information.
