QUAD UART WITH 64BYTE FIFO

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
functional description (continued)
trigger levels
The TL16C754B UART provides independent selectable and programmable trigger levels for both receiver and
transmitter DMA and interrupt generation. After reset, both transmitter and receiver FIFOs are disabled and so,
in effect, the trigger level is the default value of one byte. The selectable trigger levels are available via the FCR.
The programmable trigger levels are available via the TLR.
hardware flow control
Hardware flow control is composed of auto-CTS and auto-RTS. Auto-CTS and auto-RTS can be
enabled/disabled independently by programming EFR[7:6].
With auto-CTS, CTS must be active before the UART can transmit data.
Auto-RTS only activates the RTS output when there is enough room in the FIFO to receive data and deactivates
the RTS output when the RX FIFO is sufficiently full. The HALT and RESTORE trigger levels in the TCR
determine the levels at which RTS is activated/deactivated.
If both auto-CTS and auto-RTS are enabled, when RTS is connected to CTS, data transmission does not occur
unless the receiver FIFO has empty space. Thus, overrun errors are eliminated during hardware flow control.
If not enabled, overrun errors occur if the transmit data rate exceeds the receive FIFO servicing latency.
auto-RTS
Auto-RTS data flow control originates in the receiver block (see functional block diagram). Figure 1 shows RTS
functional timing. The receiver FIFO trigger levels used in Auto-RTS are stored in the TCR. RTS is active if the
RX FIFO level is below the HALT trigger level in TCR[3:0]. When the receiver FIFO HALT trigger level is reached,
RTS is deasserted. The sending device (e.g., another UART) may send an additional byte after the trigger level
is reached (assuming the sending UART has another byte to send) because it may not recognize the
deassertion of RTS until it has begun sending the additional byte. RTS is automatically reasserted once the
receiver FIFO reaches the RESUME trigger level programmed via TCR[7:4]. This reassertion allows the
sending device to resume transmission.
