Dear colleagues,

      I'm planning on using the 32.768kHz LSE timer, and I would like to confirm that this timer is actually built into the STM32F407 I'm using (on Keil board, MCBSTM32F400). There's no clear documentation in any of the data sheets, whether LSE is actually a built-in timer, and what's the difference to LSI.

Thanks in advance,
