I have some questions of RS485, in using NXP's MCU(LPC1518). Specific as follows:
We configured the RTS signal to provide an output enable signal to control an RS-485 transceiver(USART_CFG = 1).
But, we found the phenomenon of abnormal that DE would be Low at Sending Data Operation incidentally.It continue about 6us.
Could you have some suggestions about it ?
Thank you very much.
