For STM32F4 series, when PC14/PC is used for external crystal(32.768k), which power supply is output for crystal? What is the voltage amplitude？

Hi Sir,We want to use STM32F429IGT6's internal RTC, so we connect pin 6 to backup battery, and add a 32.768K crystal to pin8 pin9, Are there any additional details I missed?

STM32F429IGT6's RTC Hardware Design

We have a new product and the MCU is STM32F429VIT6, I checked the datasheet, it has 4 uart/4 usart, our product need to connect 6 device by uart interface, so could I use the MCU to finish the reqirement? what should i need to be considered?
