NuMicro^™ M058/M0516 Data Sheet
6.12 External Bus Interface (EBI)
6.12.1 Overview
NuMicro M051^™ series 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.
6.12.2 Features
External Bus Interface has the following functions:
1. External devices with max. 64K-byte size (8 bit data width)/128K-byte (16 bit data width)
supported
2. Variable external bus base clock (MCLK) supported
3. 8 bit or 16 bit data width supported
4. Variable data access time (tACC), address latch enable time (tALE) and address hold time
(tAHD) supported
5. Address bus and data bus multiplex mode supported to save the address pins
6. Configurable idle cycle supported for different access condition: Write command finish
(W2X), Read-to-Read (R2R)
