Functional overview
STM32L452xx
interrupt is generated if enabled. LSE failure can also be detected and generated an
interrupt.
• Clock-out capability:
– MCO: microcontroller clock output: it outputs one of the internal clocks for
external use by the application
– LSCO: low speed clock output: it outputs LSI or LSE in all low-power modes
(except VBAT).
Several prescalers allow to configure 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 80 MHz.
