EBI
Figure 6 shows the structure of the EBI.
The EBI has two basic modes of operation; Low Noise or High
Performance. In Low Noise mode the Address and Data lines are only
driven out during external accesses to reduce RF emissions
In High Performance mode the EBI operates at its fastest. This mode of
operation requires the external address and data signals from the
MC68HC08AZ0 before they are stable.
The chip-select regions are controlled by software providing the user
with a choice of four combinations.The chip-selects have a control
register which allows the chip selects to be enabled, their polarity
selected and for the appropriate number of WAIT States to be defined
for CS0 and CS1.
