6.12 External Bus Interface (EBI)
6.12.1 Overview
6.12.2 Features
NuMicro M051
NuMicro M051
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:
1.
2.
3.
4.
5.
