2.6
CPU operation is synchronized by a system clock (ø) or a subclock (ø
clock signals see section 4, Clock Pulse Generators. The period from a rising edge of ø or ø
the next rising edge is called one state. A bus cycle consists of two states 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 2-11 shows the on-chip memory access cycle.
