Bus Operations
This section provides an overview of device bus operations. The on-chip Write State Machine
(WSM) manages all erase and program algorithms. The system CPU provides control of all in-
system read, write, and erase operations of the device via the system bus.
Device commands are written to the CUI to control all of the flash memory device’s operations.
The CUI does not occupy an addressable memory location; it’s the mechanism through which the
flash device is controlled.
Bus Operations Overview
The local CPU reads and writes flash memory in-system. All bus cycles to or from the flash
memory conform to standard microprocessor bus cycles.
