Description of Flash Interrupt Operation
The Flash module uses the CCIF flag in combination with the CCIE interrupt enable bit to generate the
Flash command interrupt request. The Flash module uses the DFDIF and SFDIF flags in combination with
the DFDIE and SFDIE interrupt enable bits to generate the Flash error interrupt request. For a detailed
description of the register bits involved, refer to

Wait Mode
The Flash module is not affected if the MCU enters wait mode. The Flash module can recover the MCU
from wait via the CCIF interrupt (see
from wait via the CCIF interrupt (see
).
31.4.9
Stop Mode
If a Flash command is active (CCIF = 0) when the MCU requests stop mode, the current Flash operation
will be completed before the MCU is allowed to enter stop mode.
