Features of 512 Kbit flash memory
Flash memory writing/deleting

Flash memory control status register (FMCS)
The following three methods are provided for data writing and deleting on flash memory:
1. Parallel writer
2. Serial special-purpose writer
3. Writing/deleting by program execution
This section describes “3. Writing/deleting by program execution.”
The 512K-bit flash memory is allocated on FF
interface circuit, the memory allows read access and program access from CPU.
Writing/deleting on flash memory is performed by instruction from CPU via flash memory interface. Because
rewriting is allowed on mounted memory, modifying program and data is performed efficiently.
• 128 K words x 8 bits/64 K words x 16 bits (16 K + 8 K + 8 K + 32 K) sector configuration
• Automatic program algorithm (Embedded Algorithm
• Built-in deletion pause/deletion resume function
• Detection of completed writing/deleting by data polling and toggle bits.
• Detection of completed writing/deleting by CPU interrupt.
• Deletion is allowed on a sector-by-sector basis (sectors are combined freely).
• Number of writing/deleting operations (minimum): 10,000 times
• Sector protection
• Expanded sector protection
• Temporaly sector unprotection
• Writing and reading data is not allowed simultaneously on the flash memory.
• Data writing and deleting on the flash memory is performed by the processes as follows: Make a copy of
program on flash memory onto RAM. Then, execute the program copied on the RAM.
