The CPRGMII is operating in the forced mode of operation when the RGMII_RX_INBAND input is deasserted by setting to 0h bit CTL_EN of the CPSW_PN_MAC_CONTROL_REG_k register. In the forced mode of operation, the in-band data is ignored if present. The link status is forced high, and the duplexity and speed are determined from the CPSW_PN_MAC_CONTROL_REG_k[0] FULLDUPLEX and CPSW_PN_MAC_CONTROL_REG_k[7] GIG bits. If bit [7] GIG = 1h, then CPRGMII is operating in Gigabit mode. If bit [7] GIG is cleared (0h), then CPRGMII is operating in 100 Mbps mode.
