10.2.2. Interface

The Soft UART will have the following signal interface, exposed using _hw.tcl through Platform Designer software.

Table 55.  Clock and Reset Signal Interface
Pin Name Direction Description
clk Input

Avalon® clock sink

rst_n Input

Avalon® reset sink

Asynchronous assert, Synchronous deassert active low reset.

Interconnect fabric expected to perform synchronization – UART and interconnect is expected to be placed in the same reset domain to simplify system design

Table 56.   Avalon® -MM Agent
Pin Name Width Direction Description
addr 9 Input

Avalon® -MM Address bus

Highest addressable byte address is 0x118 so a 9-bit width is required

read   Input Avalon® -MM Read indication
readdata 32 Output Avalon® -MM Read Data Response from the agent
write   Input Avalon® -MM Write indication
writedata 32 Input Avalon® -MM Write Data
Table 57.  Interrupt Interface
Pin Name Direction Description
intr Output Interrupt signal
Table 58.  Flow Control
Pin Name Direction Description
sin Input Serial Input from external link.
sout Output Serial Output to external link.
sout_oe Output Output enable for Serial Output to external link.

sout_oe signal will be high when the UART is transmitting and low when the UART is IDLE.

Table 59.  Modem Control and Status
Pin Name Direction Description
cts_n Input Clear to Send
rts_n Output Request to Send
dsr_n Input Data Set Ready
dcd_n Input Data Carrier Detect
ri_n Input Ring Indicator
dtr_n Output Data Terminal Ready
out1_n Output User Designated Output1
out2_n Output User Designated Output2
Table 60.  DMA Sideband Signals
Pin Name Direction Description
dma_tx_ack_n Input TX DMA acknowledge
dma_rx_ack_n Input RX DMA acknowledge
dma_tx_req_n Output TX DMA request
dma_rx_req_n Output RX DMA request
dma_tx_single_n Output TX DMA single request
dma_rx_single_n Output RX DMA single request
