#RES of pin 4 of the Hitachi-UDI port connector is a signal line in which the
emulator outputs signals to the MCU.
#RES of pin 7 of the Hitachi-UDI port connector is a signal line in which the
emulator monitors the #RES signal of the MCU.
The #RES must be pulled up before it is connected to pin 7 of the Hitachi-UDI
port connector.
Connect GND of pins 8 to 10 and 12 to 14 in the Hitachi-UDI port connector to
ground in the user system.
Connect Vcc, pin 11 in the Hitachi-UDI port connector, to the power supply
(Vcc) in the user system. The amount of voltage permitted to input to the
Hitachi-UDI port connector must be within the guaranteed range of the
microcomputer.
Figure 6.6 shows the interface circuit in the emulator. Use this figure as a
reference when determining the pull-up resistance value.
In the H8S/2339, H8S/2329, and H8S/2319 series, only H8S/2339EF,
H8S/2329EF, and H8S/2319EF can be connected to the emulator. H8S/2339F,
H8S/2329F, and H8S/2319F for general use cannot be used.
