SET	(STOPBITS is valid) or RESET (STOPBITS is invalid)

◆ IS_UART_WAKEUP_SELECTION

#define IS_UART_WAKEUP_SELECTION ( __WAKE__ )

Value:

                                            (((__WAKE__) == UART_WAKEUP_ON_ADDRESS)           || \
                                            ((__WAKE__) == UART_WAKEUP_ON_STARTBIT)          || \
                                            ((__WAKE__) == UART_WAKEUP_ON_READDATA_NONEMPTY))

Ensure that UART wake-up selection is valid.

Parameters

__WAKE__ UART wake-up selection.

Return values

SET	(WAKE is valid) or RESET (WAKE is invalid)
