In-Circuit Emulator Options dialog, Vcc/Clock Setup page
No option here, as well. The POD power is provided so that the emulator can be used standalone, that
is, without being connected to a target board. As soon as the target is connected, the target power has
to be applied. Note the correct sequencing of the emulator and target power.
There is no programmable clock control available from winIDEA. Check the Renesas V850E2/Fx4
User Manual to familiarize yourself with the microcontroller clock controller.
The V850Fx4 Renesas POD (IC30741P) comes populated with the 4MHz crystal, which connects to
the Main Oscillator. Next, a 32.768 kHz quartz crystal is provided for the Sub Oscillator. If the target
application uses different main oscillator crystal than 4MHz, the crystal on the V850Fx4 Renesas POD
must be exchanged. Refer to the IC30740 POD Hardware Reference document, which comes along
with the development system, for more details on exchanging the 4MHz main oscillator crystal.
2.4 Initialization Sequence
Usually, there is no need to use initialization sequence when debugging with an In-Circuit Emulator
(ICE) a single chip application. Primarily, initialization sequence is used on On-Chip Debug systems to
initialize the CPU after reset to be able to download the code to the target (CPU or CPU external)
memory. With an ICE system, the initialization sequence may be required for instance to enable
memory access to the CPU internal EEPROM or to some external target memory, which is not
accessible by default after the CPU reset. The user can also disable CPU internal COP using
initialization sequence if there is a need for that, etc.
Initialization sequence is executed immediately after the CPU reset and then the code is downloaded.
Detailed information may be found in the Initialization Sequence help topic.
