Note 1: During boot mode, the CPU starts executing the boot program after exiting the reset state. For details, see Section
6.6, “Programming the Internal Flash Memory.”
Note 2: During flash E/W enable mode, this vector address is moved to the beginning of the internal RAM
(address H’0080 4000). For details, see Section 6.6, “Programming the Internal Flash Memory.”
