Table 45-45. SPI Timings (Continued)
Notes:
Note that in SPI master mode the SAM3X/A does not sample the data (MISO) on the opposite edge where data clocks out
(MOSI) but the same edge is used as shown in

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.
Timings are given assuming the following VDDIO supply and load.
VDDIO = 1.62V @25 pF
VDDIO = 3V @25 pF
