Strap

SPI_SPD_SEL

(PD)

This strap is used to select the speed of the SPI.

0 = 30 MHz (default)

1 = 60 MHz

Note:

If the latched value on reset is 1, this

pin is tri-stated when the chip is in the

suspend state. If the latched value on

reset is 0, this pin is driven low during

a suspend state.

See Note 2 for more information on configuration

straps.
