Two questions about nios II

1. I'm not quite sure how to use the WI and RI bits in the control register of JTAG_UART core. What's the meaning of " Indicates that the read interrupt is pending". Are there any examples that when WI and RI are 1 or 0?

2.The JTAG_UART core has fast and small version drivers. In order to enable the small version one should specify the preprocessor option -DALTERA_AVALON_JTAG_UART_SMALL. Who can tell me where to specify that?:oops:

    If you are using the Altera supplied drivers then you don't need to know about the device register definitions.
