Mode Transitions: When the mode pins and the FWE pin are set in the reset state and a reset-start is executed, the MCU
enters one of the operating modes shown in figure 19-8. 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 programmer mode.
