8.4.6.6.1 Automatic Refresh

QSPI_REFRESH defines the periodicity of the automatic refresh sequence.

Automatic refresh is enabled if the following conditions are met:

  • The QSPI is enabled (QSPI_CR.QSPIEN is written to 1).
  • QSPI_REFRESH.REFRESH is not set to 0.
  • QSPI_MR.DQSDLYEN is set.

An automatic refresh sequence of analog blocks is performed:

  • after the first QSPI enable,
  • when the internal refresh counter is set to 0 if REFRESH is not set to 0.
