20.3.4 Debug mode
When the microcontroller enters the debug mode (Cortex
®
-M4 with FPU core - halted), the
TIMx counter either continues to work normally or stops, depending on the
DBG_TIMx_STOP configuration bit in the DBG module. For more details, refer to
Section 38.16.2: Debug support for timers, watchdog, bxCAN and I

C.
20.4 TIM6 and TIM7 registers
Refer to Section 1.1 for a list of abbreviations used in register descriptions.
The peripheral registers have to be written by half-words (16 bits) or words (32 bits). Read
accesses can be done by bytes (8 bits), half-words (16 bits) or words (32 bits).
