28.4.1.2.1
Define FCCOB Contents
The FCCOB parameter fields must be loaded with all required parameters for the Flash command being
executed. Access to the FCCOB parameter fields is controlled via the CCOBIX bits in the FCCOBIX
register (see
Section
28.3.2.3).
The contents of the FCCOB parameter fields are transferred to the Memory Controller when the user clears
the CCIF command completion flag in the FSTAT register (writing 1 clears the CCIF to 0). The CCIF flag
will remain clear until the Flash command has completed. Upon completion, the Memory Controller will
return CCIF to 1 and the FCCOB register will be used to communicate any results. The flow for a generic
command write sequence is shown in
Figure
28-26.
