tsUartOpt

The options are specified by SERIAL_vInitEx(). This structure does not need to be statically allocated memory.

In principle, these options are not supported. When using them, please check the output signals with an oscilloscope or similar. The following communication settings are supported as standard.

• No hard flow

• Parity: none

• Stop bit: 1bit

• Data: 8bit

The structure must be cleared to 0 before use.

bool_t	bHwFlowEnabled	TRUE: Hardware flow enabled FALSE: Disabled
bool_t	bParityEnabled	TRUE: Parity enabled FALSE: Disabled
uint8	u8ParityType	E_AHI_UART_EVEN_PARITY: even E_AHI_UART_ODD_PARITY: odd (no need to set value if parity is disabled)
uint8	u8StopBit	E_AHI_UART_1_STOP_BIT: 1bit, E_AHI_UART_2_STOP_BIT: 1.5/2bit
uint8	u8WordLen	7: 7bit, 8: 8bit
