Table 5-3 shows functions available for various protocols on each SCC for the MC68360.
Figure 5-7 to Figure 5-10 show that not all the functions available to each SCC can be used
simultaneously due to overlaps of the register locations stored in the parameter RAM. For
example, in Figure 5-8, the SPI area overlaps the Ethernet area, which means the user can
use either SPI or Ethernet on SCC2, but not both at once.
5.3.2 Parameter RAM Usage for QMC over Several SCCs
There are two possible memory configurations for operating the QMC protocol on several
SCCs. For each SCC in QMC protocol, a global parameter area is used, consuming at most
170 bytes if every global area contains the routing tables. The time slot assignment tables
(TSATRx and TSATTx) together occupy 128 bytes. The tables for each SCC in the
parameter RAM can be duplicated, requiring 170 bytes per SCC.
Alternatively, multiple SCCs can use one set of common time slot assignment tables
(TSATRx and TSATTx), as described in Section 2.1.3, “TSATRx/TSATTx Pointers and
Time Slot Assignment Table.” One SCC RAM page uses 172 bytes, 44 bytes for registers
and 128 bytes for the common time slot assignment tables, allowing the other SCCs to use
only 44 bytes of parameter RAM for QMC protocol, freeing 128 bytes. This alternative is
referred to as ‘QMC on Multiple SCCs’ in Figure 5-7 to Figure 5-15.
