RH850/F1KH, RH850/F1KM, RH850/F1K Flash Memory User’s Manual: Hardware Interface
●The features of the flash memory are described below. See the RH850/F1K Userʼs Manual: Hardware or the RH850/F1KH, RH850/F1KM Userʼs Manual: Hardware for information on the capacity, block configuration, and addresses of the flash memory in a given product.
●Flash Memory Programming/Erasure
▲A dedicated sequencer for the flash memory (flash sequencer) executes programming and erasure via the P-Bus. Directly controlling the flash sequencer can provide better response and performance than using the code flash library and data flash library. The flash sequencer also supports the suspension and resumption of programming and erasure, and background operations (BGO)
●Security Functions
▲The flash memory incorporates hardware functions to prevent illicit tampering.
●Safety Functions
▲The flash memory incorporates hardware functions to prevent erroneous writing.
●Interrupts
▲The flash memory supports an interrupt (INTFLENDNM) to indicate completion of processing by the flash sequencer (i.e., the FSTATR.FRDY bit has been set to 1) and an error interrupt (INTFLERR) to indicate erroneous operations.
●DMA
▲The data flash memory can be programmed by using DMA.
