调用uart_enable_intr_mask()来使能指定的中断,调用uart_disable_intr_mask()来关闭制定的中断。所有中断的掩码在UART_INTR_MASK里可见。注册一个句柄用来服务中断是用uart_isr_register(),释放句柄用uart_isr_free()。一旦句柄被调用,使用uart_clear_intr_status()来清除中断状态位。
uart_enable_pattern_det_intr(UART_PORT_NUM, '\n', 1, 10000, 10, 300); I would guess the idle time is measured from the rising edge of the stop bit to the falling edge of the next start bit. This is one of my assumptions, but I can't find any information in the Technical Re...
