17.4.2.10 FMR40 Bit
The suspend function is enabled by setting the FMR40 bit to 1 (enable).
17.4.2.11 FMR41 Bit
In EW0 mode, the MCU enters erase-suspend mode when the FMR41 bit is set to 1 by a program.
The FMR41 bit is automatically set to 1 (request erase-suspend) when an interrupt request of an
enabled interrupt is generated in EW1 mode, and then the MCU enters erase-suspend mode.
Set the FMR41 bit to 0 (erase restarts) when the auto-erase operation restarts.
17.4.2.12 FMR42 Bit
In EW0 mode, the MCU enters program-suspend mode when the FMR42 bit is set to 1 by a program.
The FMR42 bit is automatically set to 1 (request program-suspend) when an interrupt request of an
enabled interrupt is generated in EW1 mode, and then the MCU enters program-suspend mode.
Set the FMR42 bit to 0 (program restart) when the auto-program operation restarts.
17.4.2.13 FMR43 Bit
When the auto-erase operation starts, the FMR43 bit is set to 1 (erase execution in progress). The
FMR43 bit remains set to 1 (erase execution in progress) during erase-suspend operation.
When the auto-erase operation ends, the FMR43 bit is set to 0 (erase not executed).
17.4.2.14 FMR44 Bit
When the auto-program operation starts, the FMR44 bit is set to 1 (program execution in progress).
The FMR44 bit remains set to 1 (program execution in progress) during program-suspend operation.
When the auto-program operation ends, the FMR44 bit is set to 0 (program not executed).
17.4.2.15 FMR46 Bit
The FMR46 bit is set to 0 (reading disabled) during auto-erase execution and set to 1 (reading
enabled) in erase-suspend mode. Do not access the flash memory while this bit is set to 0.
17.4.2.16 FMR47 BIt
Power consumption when reading flash memory can be reduced by setting the FMR47 bit to 1
(enabled).
