Register Access Schemes
The SC4000 features two address access
schemes. One is an indirect access
scheme (C_11 = 0) to reduce the num-
ber of pins required for the micropro-
cessor address bus interface from nine to
two (A_[1:0]), as shown in Figure 5. The
other is a combination of both indirect
and direct parallel access schemes (C_11
= 1). Using the combination requires
that all nine microprocessor address
pins (A_[8:0]) be used, as shown in
Figure 6.
