Figures 2.12 and 2.13 show recommended circuits for connection between the H-UDI and AUD
port connectors (36 pins) and the MCU when the emulator is in use.
Notes: 1. Do not connect anything to the N.C. pins of the H-UDI port connector.

2. The ASEMD0# pin must be 0 when the emulator is connected and 1 when the emulator
3. When a network resistance is used for pull-up, it may be affected by a noise. Separate

(1) When the emulator is used: ASEMD0# = 0
(2) When the emulator is not used: ASEMD0# = 1
Figures 2.12 and 2.13 show examples of circuits that allow the ASEMD0# pin to be
GND (0) whenever the emulator is connected by using the H-UDI/AUD probe. When
the ASEMD0# pin is changed by switches, etc., ground pin 22. Do not connect this pin
