E__)) and should be followed by an
Enable macro (i.e
__HAL_UART_ENABLE(__HANDLE
__)).
Enable RTS flow control This macro
allows to enable RTS hardware flow
control for a given UART instance,
without need to call
__HANDLE__: specifies the UART
Handle. The Handle Instance can be
USART1, USART2 or LPUART.
None
As macro is expected to be used for
modifying RTS Hw flow control
feature activation, without need for
USART instance Deinit/Init, following
conditions for macro call should be
fulfilled : UART instance should have
already been initialised (through call
of HAL_UART_Init() )macro could
only be called when corresponding
UART instance is disabled (i.e
__HAL_UART_DISABLE(__HANDL
E__)) and should be followed by an
Enable macro (i.e
__HAL_UART_ENABLE(__HANDLE
__)).
Disable RTS flow control This macro
allows to disable RTS hardware flow
control for a given UART instance,
without need to call
__HANDLE__: specifies the UART
Handle. The Handle Instance can be
USART1, USART2 or LPUART.
