11.4. CON4 SD Interface
CON 4 is an SD interface compatible with UHS-I (SDR104, maximum clock frequency: 196.36MHz). The SD signal
lines are connected to the SD/MMC controller (uSDHC1) on the i.MX7 Dual.
The power (SD_VDD) supplied to the SD card can be controlled with the SD1_RESET_B pin of the i.MX7 Dual. Power
is supplied during high level output and power is turned off with low level output.
