Notes 1: When starting the MCU in the single-chip mode, supply 4.5 V to 5.5 V to the CNVss
2: Set bits 6, 7 (main clock division ratio selection bits) at CPU mode register (003B
3: Before exiting the CPU rewrite mode after completing erase or program operation,
pin until checking the CPU rewrite mode entry flag.
always be sure to execute the read array command or reset the flash memory.
