Nonsense in STM32L452E Reference Manual, RM0394 Rev 4 - 2018!!

https://www.st.com/resource/en/reference_manual/rm0394-stm32l41xxx42xxx43xxx44xxx45xxx46xxx-advanced-armbased-32bit-mcus-stmicroelectronics.pdf

Cross-references the wrong register, should be RCC_BDCR

RM0394 Reset and clock control (RCC)  Pg 247
6.2.6 LSE clock

...

External source (LSE bypass)
In this mode, an external clock source must be provided. It can have a frequency of up to 1 MHz. You select this mode by setting the LSEBYP and LSEON bits in the AHB1 peripheral clocks enable in Sleep and Stop modes register (RCC_AHB1SMENR). The external clock signal (square, sinus or triangle) with ~50 % duty cycle has to drive the OSC32_IN pin while the OSC32_OUT pin can be used as GPIO. See Figure 14.
