Configuration
Interrupt Delivery
The property irqControl should be connected to the device which the MEC raises interrupts on, this is normally a CPU object. The connection should be made to the CPU-object’s interface of type IrqIface. Note that the CPU must support interrupts 1 through 15, this is in general case correct for SPARC based processors, but other CPUs may not be compatible.
UART Connections
Two serial interfaces exist, the UartAIface and the UartBIface, these can be connected to in order to receive data from remote serial port terminals (i.e. this is the RX direction). The uarta and uartb properties can be used to connect the TX direction of the UARTs.
Infinite UART Speed
Set config.infiniteUartSpeed to nonzero to enable infinite speed on the Tx channels. With infinite speed, a written byte is immediately forwarded to the destination device, with limited UART speed (the variable being zero) the timing due to UART scaler bits (upper 8 bits of the MecCtrlReg) will be simulated, leading to realistic byte rates over the serial port device. Note that individual bits are not transmitted only the bytes.
