11 Enhanced Secure Digital Host Controller (eSDHC)
This section describes the DC and AC electrical specifications for the eSDHC (SD/MMC) interface of the
MPC8379E.
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 sample the SD_DAT[0:3] as inputs. This behavior is true for both full-
and high-speed modes.
Note that this is a non-standard implementation, as the SD card specification assumes that in high-speed
mode, data is driven at the rising edge of the clock.
