(3) Flash Erase Code Select Register (FECS)
FECS selects download of the on-chip erasing program.
Bits 7 to 1—Reserved: These bits are always read as 0. The write value should always be 0.
Bit 0—Erase Pulse Verify Block (EPVB): Selects the erasing program.

(4) Flash Key Code Register (FKEY)
FKEY is a register for software protection that enables download of on-chip program and
programming/erasing of flash memory. Before setting the SCO bit to 1 in order to download on-
chip program or executing the downloaded programming/erasing program, these processing
cannot be executed if the key code is not written.
Bits 7 to 0—Key Code (K7 to K0): Only when H
