2. The /RESET signal in the user side is input to the 193 pin of the SH7729 or
SH7709A. Connect this pin to the Hitachi-UDI port connector as the output from
the user system.
Figure 6.3 shows the pin arrangement of the Hitachi-UDI port connector (36 pins).

The emulator monitors the GND signal of the user system and
detects whether or not the user system is connected.

Figure 6.3 Pin Arrangement of the Hitachi-UDI Port Connector (36 Pins)
Notes: 1. Handling of the TCK, TMS, TDI, TDO, /TRST, and /ASEBRKAK pins depends
on the use conditions of the Hitachi-UDI as follows:
(a)
When the user system is used by connecting the emulator, the TCK, TMS,
TDI, TDO, /TRST, and /ASEBRKAK pins must be pulled up by a
resistance of several kilo-ohms. The ASEMD0 pin must be grounded. The
AUDATA3 to AUDATA0 and /AUDSYNC pins must be pulled up by a
resistance of several kilo-ohms. The resistor of the AUDCK pin must be
terminated (pulled up and pulled down by a resistance of several kilo-
ohms).
(b)
When the user system is used independently without using the emulator
and Hitachi-UDI, the TCK, TMS, TDI, TDO, /TRST, and /ASEBRKAK
pins must be pulled up by a resistance of several kilo-ohms. The ASEMD0
pin also must be pulled up by a resistance of several kilo-ohms. The
AUDCK, AUDATA3 to AUDATA0, and /AUDSYNC pins must be pulled
up by a resistance of several kilo-ohms.
