NOTE: The diagram shows SDMA system bus writes, not data on the RXD pin. Other bus activity may occur between successive
Serial Communication Controllers (SCCs)
7.10.23.8 ETHERNET MEMORY MAP. When configured to operate in Ethernet mode, the
QUICC overlays the structure described in Table 7-5 onto the protocol-specific area of the
SCC parameter RAM described in Table 7-11.
7-246
NOTE: The receive data is sent to the CAM as it is written to system memory. The SDACK2–SDACK1 signals are used to identify the
32-bit writes. In such a case, the SDACK2–1 pins would not be asserted for other bus activity.
