10.2.2. Interface
The Soft UART will have the following signal interface, exposed using _hw.tcl through Platform Designer software.
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 |
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 |
Pin Name | Direction | Description |
---|---|---|
intr | Output | Interrupt signal |
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. |
