CHAPTER 17 FLASH MEMORY
17.5 Detailed Explanation of Writing to Erasing Flash Memory
This section describes each operation procedure of flash memory Read/Reset, Write,
Chip Erase, when a command that starts the automatic algorithm is issued.
■ Detailed Explanation of Flash Memory Write/Erase
The flash memory executes the automatic algorithm by issuing a command sequence (see Table 17.3-1 in
Section "17.3 Starting the Flash Memory Automatic Algorithm "for a write cycle to the bus to perform
Read/Reset, Write, Chip Erase operations. Each bus write cycle must be performed continuously. In
addition, whether the automatic algorithm has terminated can be determined using the data polling or other
function. At normal termination, the flash memory is returned to the read/reset state.
Each operation of the flash memory is described in the following order:
17.5.1 Setting The Read/Reset State
17.5.2 Writing Data
17.5.3 Erasing All Data (Erasing Chips)
