13 Enhanced Secure Digital Host Controller (eSDHC)
This section describes the DC and AC electrical specifications for the eSDHC (SD/MMC/SDIO) interface
of the MPC8308.
The eSDHC controller always uses the falling edge of the SD_CLK in order to drive the
SD_DAT[0:3]/CMD as outputs and rising edge to sample the SD_DAT[0:3], CMD, CD and WP as inputs.
This behavior is true for both full and high speed modes.
