11.1.7.3.2 QSPI Timings

For the QSPI0 instance, the timings shown in the tables below are provided in the following domains:
  • 1.8V domain: VDDQSPI from 1.7V to 1.9V, maximum external capacitor: 10 pF, Drive = 1, Slewrate = 0
  • 3.3V domain: VDDQSPI from 3.0V to 3.6V, maximum external capacitor: 10 pF, Drive = 0, Slewrate = 0
