Figure 7-2 Basic Diagram of Flash Module

All Flash operations are initiated by transferring command sequences to the Flash that

are based on the JEDEC standard. The command sequences to the Flash are high-level

commands such as “Erase Sector”. State transitions during execution of the commands,

such as termination of command execution or errors, are indicated by status flags and

maskable interrupts. Command sequences are normally written to the PMU by the CPU

but can also be issued by the PCP or the DMA controller.
