19.15.3 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 19-37. 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.
Notes: Only make a transition between user mode and user program mode when the CPU is
