The flash memory version has two modes—CPU rewrite and standard serial I/O—in which its flash
memory can be operated on.
Table 17.1 outlines the performance of flash memory version (see “Table 1.1 Performance” for the items
not listed on Table 17.1).
Item
User ROM area is rewritten by executing
software commands from the CPU.
