## Description

Many parameters of the USART driver are configured using the ARM_USART_Control function.

The various USART control codes define:

- USART Mode Control specifies USART mode
- USART Data Bits defines the number of data bits
- USART Parity Bit defines the parity bit
- USART Stop Bits defines the number of stop bits
- USART Flow Control specifies RTS/CTS flow control
- USART Clock Polarity defines the clock polarity for the synchronous mode
- USART Clock Phase defines the clock phase for the synchronous mode
- USART Miscellaneous Control specifies additional miscellaneous controls

Refer to the ARM_USART_Control function for further details.
