To set the FMR01, FMR02, FMR11 or FMR16 bit to “1”, set the subject bit to “1” immediately after setting
to “0”. Do not generate an interrupt or a DMA transfer between the instruction to set the bit to “0” and the
instruction to set the bit to “1”. When the PM24 bit is set to “1” (NMI funciton), apply a high-level (“H”)
signal to the NMI pin to set those bits.
In EW1 mode, make sure that no DMA transfers will occur while the FMR00 bit in the FMR0 register is set
to "0" (during the auto program or auto erase period).
As the number of programming/erasure times increases, so does the execution time for software com-
mands (Program, and Block Erase).
The software commands are aborted by hardware reset 1, hardware reset 2, NMI interrupt, and watchdog
timer interrupt. If a software command is aborted by such reset or interrupt, the affected block must be
erased before reexecuting the aborted command.
