10.4.3
Figure 10-30 provides an example connecting parallel
EEPROM to the PMP. Figure 10-31 demonstrates a
slight variation to this, configuring the connection for
16-bit data from a single EEPROM.

10.4.4
The PMP module can be configured to connect to a
typical LCD controller interface, as displayed in
Figure 10-32. In this case, the PMP module is config-
ured for active-high control signals since common LCD
displays require active-high control.
