Table 6-3. Major Functions of Flash Memory Programming
Flashpro III
Used to stop write operation and detect transmission cycle.
Compares the entire memory contents with the input data.
Erases the entire memory contents.
Checks the deletion status of the entire memory.
Performs write to the flash memory based on the write start address and the number of data
to be written (number of bytes).
Performs continuous write based on the information input with high-speed write operation.
Used to confirm the current operating mode and operation end.
Sets the frequency of the resonator.
Sets the memory erase time.
Sets the communication rate for UART mode
Sets standard/high-speed mode for I
Outputs the device name and memory capacity, and device block information.
