4.11.2 CPU access timing (when a multiplex bus is set)
4.11.2.1 CPU access write timing (when a multiplex bus is set)
4.11.2.2 CPU access read timing (when a multiplex bus is set)
Note 2-1: The control signal when writing data is a combination of CS_N, WR1_N, and WR0_N.
Note 2-2: The control signal when reading data is a combination of CS_N and RD_N.
Note 2-3: RD_N, WR0_N, and WR1_N should not be timed to fall when CS_N is rising. Similarly, CS_N should not be timed to
fall when RD_N or WR0_N, and WR1_N are rising. In the above instances, an interval of at least 10ns must be left open.
