Analog Devices SHARC ADSP-214 Series User Manual

ADSP-214xx SHARC Processor Hardware Reference A-247
Registers Reference
Interrupt Identification Registers (UART0IIR,
UART0IIRSH)
For legacy reasons, the UART interrupt identification register (UART0IIR,
shown in Figure A-139) still reflect the UART interrupt status. Legacy
operation may require bundling all UART interrupt sources to a single
interrupt channel and servicing them all by the same software routine.

Table A-129. UART0IER Register Bit Descriptions (RW)
Bit Name Description
0 UARTRBFIE Enable Receive Buffer Full Interrupt.
0 = No interrupt

0 = No interrupt
1 = Generate TX interrupt if THRE bit in UART_LSR is set
2UARTLSIEEnable RX Status Interrupt.
0 = No interrupt
1 = Generate line status interrupt if any of UART_LSR[4–1] is set
3UARTTXFIEEnable Transmit Complete Interrupt.
0 = No interrupt
