Normal read/write operation is used for all bus access when page read/write access is disabled
(PRENB = 0, PWENB = 0). Even when page read/write access is enabled (PRENB = 1, PWENB
= 1), normal read/write operation is employed in cases where page access cannot be used. Figure
9.2 shows the basic operation of the external bus control signals in read operation, and figure 9.3
shows the basic operation of these signals in write operation.
