19.4.2.10 FMR40 Bit
19.4.2.11 FMR41 Bit
19.4.2.12 FMR42 Bit

The suspend function is enabled by setting the FMR40 bit to 1 (enable).
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.
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.
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).
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).
The FMR46 bit is set to 0 (reading disabled) during auto-program or auto-erase execution and set to 1 (reading
enabled) in suspend mode. Do not access the flash memory while this bit is set to 0.
Power consumption when reading the flash memory can be reduced by setting the FMR47 bit to 1 (enabled) in
low-speed clock mode (XIN clock stops) and low-speed on-chip oscillator mode (XIN clock stops).
