DBG_STOP=B_0x0, DBG_STANDBY=B_0x0
DBGMCU configuration register
DBG_STOP | Debug Stop mode Debug options in Stop mode. 0 (B_0x0): All clocks disabled, including FCLK and HCLK. Upon Stop mode exit, the CPU is clocked by the HSI internal RC oscillator. 1 (B_0x1): FCLK and HCLK running, derived from the internal RC oscillator remaining active. If SysTick is enabled, it may generate periodic interrupt and wake up events.Upon Stop mode exit, the software must re-establish the desired clock configuration. |
DBG_STANDBY | Debug Standby and Shutdown modes Debug options in Standby or Shutdown mode. 0 (B_0x0): Digital part powered. From software point of view, exiting Standby and Shutdown modes is identical as fetching reset vector (except for status bits indicating that the MCU exits Standby) 1 (B_0x1): Digital part powered and FCLK and HCLK running, derived from the internal RC oscillator remaining active. The MCU generates a system reset so that exiting Standby and Shutdown has the same effect as starting from reset. |
