SAM4S [DATASHEET]

11100E–ATARM–24-Jul-13

Notes: 1. 3.3V domain: V

VDDIO 

from 2.85V to 3.6V, maximum external capacitor = 40 pF.

2. 1.8V domain: V

VDDIO 

from 1.65V to 1.95V, maximum external capacitor = 20 pF.

Note that in SPI Master Mode the SAM4S does not sample the data (MISO) on the opposite edge where data clocks out (MOSI) 
but the same edge is used. This is 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.
