HT-IDE3000 Configuration Option description:
Sys Freq: Do not select the
″
Internal
″
option. This is because the ICE system
frequency is determined by the Interface Card settings.
•
LED description:
LED1:
Yellow LED, when illuminated this indicates that the system is in its
Active condition, when extinguished this indicates that the system in the
Suspend condition.
LED2:
Red LED, when illuminated this indicates that the system frequency is
12MHz.
LED3:
Green LED, when illuminated this indicates that the system frequency is
6MHz.
•
Jumper and Push Button description:
J1 and J3: USB connectors.
J6:
The frequency selection jumper. When in position 1-2, the 12MHz
frequency is selected, when in position 2-3 the 6MHz frequency is
selected. If the 6MHz frequency is selected, then the SYSCLK flag in
the SCC register must be set to
″
1
″
, if the 12MHz frequency is selected
then the SYSCLK flag must be set to
″
0
″
.
J7 and J8: When using the ADC, to increase its flexibility an Internal Reference
Voltage or an External Reference Voltage can be used. When using the
Internal Reference Voltage, the ADREF flag in the USR register should
be set to
″
1
″
. Also J7 and J8 should be placed in position 2~3. If an
External Reference Voltage is used, then the ADREF flag should be set
to
″
0
″
and J7 and J8 should be placed in position 1~2. The VRH input is
via PB7 while the VRL input is via PB6.
S1:
RESET input which corresponds to the MCU reset
•
Target board interface description:
For interfacing to the user target board a choice of four connectors, U4, U5, U12,
and J9 are provided.
