Low-power management reset
There are two ways to generate a low-power management reset:
1.
2.
For further information on the User Option Bytes, refer to the STM32F10xxx Flash
programming manual.
Power reset
A power reset is generated when one of the following events occurs:
1.
2.
A power reset sets all registers to their reset values except the Backup domain (see
Figure
These sources act on the NRST pin and it is always kept low during the delay phase. The
RESET service routine vector is fixed at address
details, refer to
Figure 10. Reset circuit
Backup domain reset
The backup domain has two specific resets that affect only the backup domain (see
Figure
A backup domain reset is generated when one of the following events occurs:
1.
2.
Reset generated when entering Standby mode:
This type of reset is enabled by resetting nRST_STDBY bit in User Option Bytes. In this
case, whenever a Standby mode entry sequence is successfully executed, the device
is reset instead of entering Standby mode.
Reset when entering Stop mode:
This type of reset is enabled by resetting NRST_STOP bit in User Option Bytes. In this
case, whenever a Stop mode entry sequence is successfully executed, the device is
reset instead of entering Stop mode.
Power-on/power-down reset (POR/PDR reset)
