USART_disable_TX

Description

Disable the USART transmiter hardware. This prevents the USART from sending any more data. Disabling the transmiter while the USART is in the process of sending data will abort the current transition.

Do not disable the USART transmiter hardware as a means of implementing flow control. This would require that the transmiter shift register is contsnatly polled to check when it is safe to disable. A much better solution is to disable the transmiter interrupt generator (and keeping it disabled). This will allow the current data byte being transmited to be completed and no new data to be send.
