4.5.2 FlexSPI parameters

Measurements are with a load 15 pf and input slew rate of 1 V/ns.

4.5.2.1 FlexSPI input/read timing

There are four sources for the internal sample clock for FlexSPI read data:

• Dummy read strobe generated by FlexSPI controller and looped back internally (FlexSPI

n_MCR0[RXCLKSRC] = 0x0)

• Dummy read strobe generated by FlexSPI controller and looped back through the DQS pad (FlexSPI

n_MCR0[RXCLKSRC]

= 0x1)

• Read strobe provided by memory device and input from DQS pad (FlexSPI

n_MCR0[RXCLKSRC] = 0x3)

The following sections describe input signal timing for each of these four internal sample clock sources.
