E8a Emulator Section 5 Examples of E8a Connections

(2) In single power supply and memory expansion mode

Figure 5.2 Example of an E8a Connection (Single Power Supply and Memory Expansion Mode)

Notes:

1. For details on setting pins P64 and P65 refer to number 1 of “Points to Remember” on page 9.

2. The HOLD

signal cannot be used. Pull up P55 on the user system.

3. P50 is used as the WRL#/WR# pin. The E8a emulator outputs “H” to the CE pin when going to boot mode (resetting

the MCU). In other cases, the CE pin is in a Hiz state. This prevents signal collision between the E8a emulator and

the MCU. The WRL#/WR# pin does not affect the memory because the pin has a low active signal.
