Figure 5-28
Table 5-11 shows the timing values and definitions.
Table 5-11
*Where f is the clock frequency.
The SPI Electrical Interface is identical to MultiMediaCard mode with the exception of the
programmable card output-drivers option, which is not supported in SPI mode.
SPI Bus operating conditions are identical to MultiMediaCard mode.
SPI Bus timing is identical to MultiMediaCard mode. The timing of the CS signal is the
same as any other card input.
