Description
External interrupt/event controller (EXTI)
The external interrupt/event controller consists of 19 edge detectors lines used to generate
interrupt/event requests. Each line can be independently configured to select the trigger
event (rising edge, falling edge, both) and can be masked independently. A pending register
maintains the status of the interrupt requests. The EXTI can detect external line with pulse
width lower than the Internal APB2 clock period. Up to 51 GPIOs are connected to the 16
external interrupt lines.
Clocks and startup
System clock selection is performed on startup, however the internal RC 8 MHz oscillator is
selected as default CPU clock on reset. An external 4-16 MHz clock can be selected, in
which case it is monitored for failure. If failure is detected, the system automatically switches
back to the internal RC oscillator. A software interrupt is generated if enabled. Similarly, full
interrupt management of the PLL clock entry is available when necessary (for example on
failure of an indirectly used external crystal, resonator or oscillator).
Several prescalers allow the configuration of the AHB frequency, the High Speed APB
(APB2) and the low Speed APB (APB1) domains. The maximum frequency of the AHB and
the APB domains is 48 MHz. See Figure 2 for details on the clock tree.
Boot modes
At startup, boot pins are used to select one of five boot options:
●
Boot from User Flash
●
Boot from System Memory
●
Boot from embedded SRAM
The boot loader is located in System Memory. It is used to reprogram the Flash memory by
using USART1. For further details please refer to AN2606.
Power supply schemes
●
VDD = 2.0 to 3.6 V: External power supply for I/Os and the internal regulator.
Provided externally through VDD pins.
●
VSSA, VDDA = 2.0 to 3.6 V: External analog power supplies for ADC, Reset blocks, RCs
and PLL (minimum voltage to be applied to VDDA is 2.4 V when the ADC is used).
VDDA and VSSA must be connected to VDD and VSS, respectively.
●
VBAT = 1.8 to 3.6 V: Power supply for RTC, external clock 32 kHz oscillator and backup
registers (through power switch) when VDD is not present.
For more details on how to connect power pins, refer to Figure 8: Power supply scheme.
