47.18.3 HSMCI
The High Speed MultiMedia Card Interface (HSMCI) supports the MultiMedia Card (MMC) Specification V4.3, the SD
Memory Card Specification V2.0, the SDIO V2.0 specification and CE-ATA V1.1.
47.18.4 EMAC
47.18.4.1 Timing conditions
47.18.4.2 Timing constraints
Note: 1. For EMAC output signals, minimum and maximum access times are defined. The minimum access time is
the time between the EDMC rising edge and the signal change. The maximum access timing is the time
between the EDMC rising edge and the signal stabilizes. Figure 47-24 illustrates minimum and maximum
accesses for EMAC3.
