5.19 External Bus Interface (EBI)
5.19.1 Overview
5.19.2 Features
The NuMicro™ NUC130/NUC140 LQFP-64 and LQFP-100 package equips an external bus
interface (EBI) for external device used.
To save the connections between external device and this chip, EBI support address bus and
data bus multiplex mode. And, address latch enable (ALE) signal supported differentiate the
address and data cycle.
External Bus Interface has the following functions:
