But you really should practice being more precise. It was clear from the context what you are asking. But it would be mo' better to say, "the CC2420 can be accessed via its SPI bus implemented by USART0 running in SPI mode while at the same time USART1 is running in UART mode". If I didn't already know what you are talking about I would have to say know because a USART module can't be running in SPI and UART mode simultaneously. Practice clearer communications. I assume english isn't your first language (your name), very good english by the way. eric
