PARALLEL EEPROM EXAMPLE
Figure 11-30 shows an example connecting parallel
EEPROM to the PMP. Figure 11-31 shows a slight
variation to this, configuring the connection for 16-bit
data from a single EEPROM.

LCD CONTROLLER EXAMPLE
The PMP module can be configured to connect to a
typical LCD controller interface, as shown in
Figure 11-32. In this case the PMP module is config-
ured for active-high control signals since common LCD
displays require active-high control.
