annotate Common/Drivers/STM32F4xx_HAL_Driver/Src/stm32f4xx_ll_usart.c @ 338:b6a59e93cc91 PressureMeasure_Improvment

Added function to avoid divemode activation during Landing: Divemode is activated in case of 100mBar difference surface to abiente pressure. This might happen during landing => Added (in sleep mode only) a check for this scenario and increased dive mode activation limit
