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

11.4.4 LCD CONTROLLER EXAMPLE
The PMP module can be configured to connect to a
typical LCD controller interface, as displayed 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.
