64.6.8.1 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 or QSPI_PCALCFG.DAPCAL is not 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.
