Location
The ATCUART100 peripheral model is located in an Imperas/OVP installation at the VLNV: andes.ovpworld.org / peripheral / ATCUART100 / 1.0.
Peripheral Instance Parameters
This model accepts the following parameters:
Table : Peripheral Parameters
| Name | Type | Description |
|---|
| finishOnDisconnect | bool | If set, disconnecting the port will cause the simulation to finish |
| outfile | string | Name of file to write device output |
| portFile | string | If portnum was specified as zero, write the port number to this file when it's known |
| log | bool | If specified, serial output will go to simulator log |
| console | bool | If specified, port number is ignored, and a console pops up automatically |
| portnum | uns32 | If set, listen on this port. If set to zero, allocate a port from the pool and listen on that. |
| infile | string | Name of file to use for device source |
| charmode | bool | Description Set to true when the port is used to connect to a Telnet program and character mode is desired rather than the default Telnet line mode. When set to true a Telnet command sequence is sent at startup that configures the Telnet program into character mode. In addition null bytes are stripped from the data received. |
| simulatebaud | bool | Description Set to true to simulate baud delay determined by the Divisor Latch register value and reference clock frequency. Set to false to run without delay - next read data is made available immediately upon read of Receiver Buffer Register. Defaults to false |
| refClkFreq | uns32 | Frequency (in hertz) of reference clock rate used in baud rate calculation |
| fifoSize | uns32 | Size of fifos |
| uart16450 | bool | Run in 16450 mode (no FIFOs) |
| connectnonblocking | bool | If set, simulation can begin before the connection is made |
| xchars | uns32 | Width of console in characters |
| ychars | uns32 | Height of console in characters |
| record | string | Record external events into this file |
| replay | string | Replay external events from this file |
Net Ports
This model has the following net ports:

| Name | Type | Must Be Connected | Description |

| resetNet | input | F (False) | Reset signal |
Bus Slave Ports
This model has the following bus slave ports:
Bus Slave Port: bport1

| ab_MCR | 0x30 | 32 | Modem Control Register | | |
| ab_LCR | 0x2c | 32 | Line Control Register | | |
| ab_FCR | 0x28 | 32 | FIFO ControlRegister | | |
| ab_IIR | 0x28 | 32 | Interrupt Identification Register | | |
| ab_IER_DLM | 0x24 | 32 | Interrupt Enable Register / Divisor Latch MSB | | |
| ab_THR_DLL | 0x20 | 32 | Transmitter Holding Register / Divisor Latch LSB | | |
| ab_RBR_DLL | 0x20 | 32 | Receiver Buffer Register / Divisor Latch LSB | | |
| ab_OSCR | 0x14 | 32 | Over Sample Control Register | | |
| ab_CFG | 0x10 | 32 | Hardware Configure Register | | |
| ab_IDREV | 0x0 | 32 | ID and Revision Register | | |
| ab_LSR | 0x34 | 32 | Line Status Register | | |
| ab_MSR | 0x38 | 32 | Modem Status Register | | |
| ab_SCR | 0x3c | 32 | Scratch Register | | |
