Section 2 CPU
2.6
CPU operation is synchronized by a system clock ( ) or a subclock (
edge of or
three states. The cycle differs depending on whether access is to on-chip memory or to on-chip
peripheral modules.
2.6.1
Access to on-chip memory takes place in two states. The data bus width is 16 bits, allowing access
in byte or word size. Figure 2.9 shows the on-chip memory access cycle.
