These registers select the configurations during run and non-run modes for each peripheral.

Field
Description
DBG_F
Peripheral control in debug mode — This bit controls the state of the peripheral in debug mode.
0 Peripheral state depends on RUN_CFG/LP_CFG bits and the device mode.
1 Peripheral is frozen if not already frozen in device modes.
NOTE
This feature is useful to freeze the peripheral state while
entering debug. For example, this may be used to prevent a
reference timer from running while making a debug accesses.
LP_CFG
Peripheral configuration select for non-run modes — These bits associate a configuration as defined in the
ME_LP_PC0…7 registers to the peripheral.
000 Selects ME_LP_PC0 configuration
001 Selects ME_LP_PC1 configuration
010 Selects ME_LP_PC2 configuration
011 Selects ME_LP_PC3 configuration
100 Selects ME_LP_PC4 configuration
101 Selects ME_LP_PC5 configuration
110 Selects ME_LP_PC6 configuration
111 Selects ME_LP_PC7 configuration
RUN_CFG
Peripheral configuration select for run modes — These bits associate a configuration as defined in the
ME_RUN_PC0…7 registers to the peripheral.
000 Selects ME_RUN_PC0 configuration
001 Selects ME_RUN_PC1 configuration
010 Selects ME_RUN_PC2 configuration
011 Selects ME_RUN_PC3 configuration
100 Selects ME_RUN_PC4 configuration
101 Selects ME_RUN_PC5 configuration
110 Selects ME_RUN_PC6 configuration
111 Selects ME_RUN_PC7 configuration
25.4 Functional Description
25.4.1 Mode Transition Request
The transition from one mode to another mode is normally handled by software by accessing the mode
control ME_MCTL register. But in case of special events, mode transition can be automatically managed
