When the RX L2 is disabled (MII_RT_RXCFG0/1[4] RX_L2_ENn = 0h, where n = 0 or 1), the RX L2 banks can be used as a generic scratch pad. In scratch pad mode, RX L2 Bank0 and RX L2 Bank1 operate like simple read/write memory mapped registers. All XFR size and start operations are supported. RX_RESET has no effect in this mode. This mode is shown in Figure 7-90.
