      Description

      The post reset event (eCIFX_TOOLKIT_EVENT_POSTRESET) is intended to be used by host systems, if they need some special hardware settings until they are able to access the netX DPM (e.g. RAM timing or SPI controller settings for SPM access).
      The function is called too late (see cifXStartRAMDevice()) because first DPM accesses are done rigth after the reset in cifXHardwareReset().

      Example:
      Using SPM the netX needs 2 "dummy reads" via SPM before valid data are delivered. eCIFX_TOOLKIT_EVENT_POSTRESET is called in cifXStartRAMDevice() but first access takes place in cifXHardwareReset() which is before.
