3.3-V DUAL UART WITH 64-BYTE FIFO
SLLS405A – DECEMBER 1999 – REVISED AUGUST 2000

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
functional description (continued)
software flow control example
Assumptions: UART1 is transmitting a large text file to UART2. Both UARTs are using software flow control with
single character Xoff (0F) and Xon (0D) tokens. Both have Xoff threshold (TCR [3:0]=F) set to 60 and Xon
threshold (TCR[7:4]=8) set to 32. Both have the interrupt receive threshold (TLR[7:4]=D) set to 52.
UART1 begins transmission and sends 52 characters, at which point UART2 will generate an interrupt to its
processor to service the RCV FIFO, but assume the interrupt latency is fairly long. UART1 will continue sending
characters until a total of 60 characters have been sent. At this time UART2 will transmit a 0F to UART1,
informing UART1 to halt transmission. UART1 will likely send the 61st character while UART2 is sending the
Xoff character. Now UART2 is serviced and the processor reads enough data out of the RCV FIFO that the level
drops to 32. UART2 will now send a 0D to UART1, informing UART1 to resume transmission.

interrupts
The TL16C752B has interrupt generation and prioritization (6 prioritized levels of interrupts) capability. The
interrupt enable register (IER) enables each of the 6 types of interrupts and the INT signal in response to an
interrupt generation. The IER can also disable the interrupt system by clearing bits 0–3, 5–7. When an interrupt
is generated, the IIR indicates that an interrupt is pending and provides the type of interrupt through IIR[5–0].
Table 4 summarizes the interrupt control functions.
