25.3.3.3 FMR02 Bit
0
The FMR00 bit indicates the flash memory operating state. It is set to "0" while the program, block
erase, erase all unlocked block, lock bit program, or read lock bit status command is being executed;
otherwise, it is set to "1".
The microcomputer can accept commands when the FMR01 bit is set to "1" (CPU rewrite mode). Set
the FMR05 bit to "1" (user ROM area access) as well if in boot mode.
The lock bit is invalid by setting the FMR02 bit to "1" (lock bit disabled). (Refer to 25.3.6 Data Protect
Function.) The lock bit is valid by setting the FMR02 bit to "0" (lock bit enabled).
The FMR02 bit does not change the lock bit status but disables the lock bit function. If the block erase
or erase all unlocked block command is executed when the FMR02 bit is set to "1", the lock bit status
changes "0" (locked) to "1" (unlocked) after command execution is completed.

Do not generate an interrupt or a DMA transfer between setting the FMR11 bit to "0" and setting it to "1".
Set it while the NMI pin is held "H".
If the FMR01 bit is set to "0", the FMR01 bit and FMR11 bit are both set to "0".
