Provision for a series
resistor (0 Ω) for MMC1_CLK (close to processor pin) and external pulldown
resistor for MMC1_CLK signal (close to device or SD Card).
Provide external pullup
resistors for the data lines (DAT0:3) and CMD signal connected to the
VDDSHV5 (Dual-voltage IO) supply rail close to the SD Card socket.
Provide external pullup
resistors for the CD and WP signals connected to the VDDSHV0 (Dual-voltage
IO) supply rail close to the SD Card socket.
