11 Enhanced Secure Digital Host Controller (eSDHC)

This section describes the DC and AC electrical specifications for the eSDHC (SD/MMC) interface of the

MPC8378E.

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.
