Flash Memory Operating Modes
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 17-34. 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.
