SDIO MMC SDR Mode Timing at 1.8 V

Timing is specified at 1.62 V IOVDD with voltage scaling disabled. Slew rate for SD_CLK set to 7, all other GPIO set to 6, DRIVES-

TRENGTH = STRONG for all pins. SDIO_CTRL_TXDLYMUXSEL = 1. Loading between 5 and 10 pF, between 10 and 20 pF, or be-

tween 20 and 30 pF on all pins.
