CHAPTER 8 MODE SETTING
8.3
Mode Data
The mode data is at memory location FFFFDF
H
, and is used to specify the operation
after a reset sequence. The mode data is automatically fetched to the CPU.
■
Mode Data
During a reset sequence, the mode data at address FFFFDF
H
is fetched to the mode register in the CPU.
The CPU uses the mode data to set the memory access mode.
The contents of the mode register can only be changed during the reset sequence. The settings in the
register take effect after the reset sequence.
Figure 8.3-1 shows the mode data configuration.

Bus Mode Setting Bits
The bus mode setting bits specify operating mode after a reset sequence. Table 8.3-1 lists the relationship
between the bits and functions.
Note:
Because the MB90460/465 series is only used in single-chip mode, set MD2, MD1, MD0 to 011
B
and
set M1, M0 to 00
B
