SCI禁用FIFO;每进一次串口中断只能从SCIRXBUF接收一个字节数据吗?
Susan Yang:
The SCI receives a complete frame and transfers the data in the RXSHF register to the SCIRXBUF register. This action sets the RXRDY flag (SCIRXST, bit 6) and initiates an interrupt.
SCIRXBUF是一个16bit的buffer

Shaoxiong Guo:
但是只有0~7bit是数据位
SCI禁用FIFO;每进一次串口中断只能从SCIRXBUF接收一个字节数据,是这样吧

Susan Yang:
是的,您的理解是正确的
