在CC111x中,USART有UART和SPI两种模式,请问:
一、在同一个USART外设中,UART和SPI模块可以同时运行使用吗?
二、如上述问题可行,那么在引脚不冲突的情况下,USART0和USART1中的UART0、SPI0、UART1、SPI1 4个外设可以同时运行使用吗?

同一时间,只能同时开启一种外设,同时只能开启一个USART。

有提到:
USART0 and USART1 are serial communications interfaces that can be operated separately in either asynchronous UART mode or in synchronous SPI mode. The two USARTs are identical in functionality but are assigned to separate I/O pins. Refer to Section 12.4 on Page 90 for I/O configuration.
