When the FMR11 bit is set to 0 (EW0 mode), the flash memory enters EW0 mode.
When the FMR11 bit is set to 1 (EW1 mode), the flash memory enters EW1 mode.
The FMR16 bit is a read-only bit indicating the execution result of the read lock bit status command.
When a block, on where the read lock bit status command is executed, is locked, the FMR16 bit becomes 0.
When a block, on where the read lock bit status command is executed, is unlocked, the FMR16 bit becomes 1.

NOTE:

1.
To set the FMR11 bit to 1, write a 1 to the FMR11 bit immediately after writing a 0 to the bit while the FMR01 bit is set to 1.
Write the value in 8-bit units. Do not generate an interrupt or a DMA or DMACII transfer between these two settings. Set the
FMR11 bit while "H" is applied to the NMI pin. When the FMR01 bit is set to 0, the FMR11 bit also becomes 0.
