An: ErrorStatus enumeration value:
SUCCESS: USART registers related to Clock settings
are initialized according to USART_ClockInitStruct
content
ERROR: Problem occurred during USART Registers
initialization
As some bits in USART configuration registers can only be
written when the USART is disabled (USART_CR1_UE bit
=0), USART IP should be in disabled state prior calling this
function. Otherwise, ERROR result will be returned.

default value.
USART_ClockInitStruct: pointer to a
LL_USART_ClockInitTypeDef structure whose fields will be
set to default values.
