MMC Card Connections
NOTE: The MMC specification imposes the following impedance limits
EMIF02-MMC R1/R2/R3/R4=47R
UEME includes a 13k pullup between GEN28IO2 (command) and VAUX1
Command pullup resistance 4.7k to 100k
so EMIF02-MMC R10 is left unconnected. UEME has no pullup on GEN28IO3 (MMC data)
Data pullup resistance 50k to 100k
