Configuration Pins Speed Select Pins SPD[2:0] There are three port-speed selection pins that select the initial speed of the RapidIO ports (see Table 1). The RESET setting can be overridden by programming the PLL n Control 1 Register and Lane n Control Register (for more information, see “Lane and Port Speeds” in the CPS-1848 User Manual). Quadrant Configuration Pins QCFG[7:0] There are eight quadrant configuration selection pins, QCFG[7:0], or two pins per quadrant (see Figure 2). These pins configure the device’s power-up settings for port width and lane to port mapping. After power-up these settings can be changed by updating the Quadrant Configuration Register (for more information, see “Lane to Port Mapping” in the CPS-1848 User Manual).
