Mode Transitions: When the mode pins are set in the reset state and a reset-start is executed, the
chip enters one of the operating modes shown in figure 19.3. In user mode, flash memory can be
read but not programmed or erased.
Flash memory can be programmed and erased in boot mode, user program mode, and PROM
mode.
