34 / 274 page  Mitsubishi microcomputers M16C / 62A Group SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER Bus Control 34 Figure 1.9.6. Typical bus timings using software wait Output Input Address Address < Separate bus (with wait) > BCLK Read signal Write signal Data bus BCLK Read signal Address bus/ Data bus Chip select (Note 2) Address Address Data output Address Address Input ALE < Multiplexed bus > Write signal BCLK Read signal Write signal Address bus (Note 2) Address Address Bus cycle (Note 1) < Separate bus (no wait) > Output Data bus Input Note 1: These example timing charts indicate bus cycle length. After this bus cycle sometimes come read and write cycles in succession. Note 2: The address bus and chip select may be extended depending on the CPU status such as that of the instruction queue buffer.
