(erase suspend mode)
NOTES:
1. Set the FMR40 bit to 1 immediately after setting it first to 0. Do not generate any interrupt or DMA
transfer between setting the bit to 0 and setting it to 1. Set by program in space other than the flash
memory in EW mode 0.
2. The FMR41 bit is valid only when the FMR40 bit is set to 1. The FMR41 bit can be written only
between executing an erase command and completing erase (this bit is set to 0 other than the
above duration). The FMR41 bit can be set to 0 or 1 by program in EW mode 0. In EW mode 1, the
FMR41 bit is automatically set to 1 when the FMR40 bit is 1 and a maskable interrupt is generated
during erasing. The FMR41 bit cannot be set to 1 by program (it can be set to 0 by program).
