UART Interrupts
There are six CMSDK UARTs in the system, each with the following interrupt pins:
•
TXINT
•
RXINT
•
TXOVRINT
•
EXOVRINT
•
UARTINT
The TXINT, RXINT and UARTINT interrupt signals of each UART drive a single interrupt input of the SSE-
300 Example Subsystem. In addition, the TXOVERINT and EXOVRINT interrupt signals of all six UARTs,
twelve signals in all, are logically ORed together to drive IRQ[47].
