4.2 Recommended Circuit (14-Pin Type)
Figure 4.2 shows a recommended circuit between the H-UDI port connector and the MCU.
Notes: 1. Do not connect anything to the N.C. pin of the H-UDI port connector.

When the emulator is used: /ASEMD0 = low (ASE mode)
When the emulator is not used: /ASEMD0 = high (normal mode)
