26.4.2.5 Load Data Field Command

The Load Data Field command is executed to provide FCCOB parameters for multiple P-Flash blocks for

a future simultaneous program operation in the P-Flash memory space.

Upon clearing CCIF to launch the Load Data Field command, the FCCOB registers will be transferred to

the Memory Controller and be programmed in the block speciﬁed at the global address given with a future

Program P-Flash command launched on a P-Flash block. The CCIF ﬂag will set after the Load Data Field

operation has completed. Note that once a Load Data Field command sequence has been initiated, the Load

Data Field command sequence will be cancelled if any command other than Load Data Field or the future

Program P-Flash is launched. Similarly, if an error occurs after launching a Load Data Field or Program

P-Flash command, the associated Load Data Field command sequence will be cancelled.
