104 / 818 page  Section 2 CPU Rev.3.00 Mar. 26, 2007 Page 62 of 772 REJ09B0355-0300 2.9 Basic Timing 2.9.1 Overview The H8S/2000 CPU is driven by a system clock, denoted by the symbol φ. The period from one rising edge of φ to the next is referred to as a "state." The memory cycle or bus cycle consists of one, two, or three states. Different methods are used to access on-chip memory, on-chip supporting modules, and the external address space. 2.9.2 On-Chip Memory (ROM, RAM) On-chip memory is accessed in one state. The data bus is 16 bits wide, permitting both byte and word transfer instruction. Figure 2.17 shows the on-chip memory access cycle. Figure 2.18 shows the pin states. Internal address bus Internal read signal Internal data bus Internal write signal Internal data bus φ Bus cycle T1 Address Read data Write data Read access Write access Figure 2.17 On-Chip Memory Access Cycle |
