several buttons pressed simultaneously. If that combination happens, then the vSys_Shutdown() is invoked and
the IDE chain would be able to connect to the part again. That would satisfy the power cycling requirement without
actually cycling the physical power to the device.
2.9. Notes about USB Adapter Use
The following facts are worth noting when using the IDE debug chain:
1. Whenever the Reset button is pressed on the IDE, the system reset is invoked and the part goes through
2. Every time the new code, in OMF or HEX format, is downloaded to the part through the IDE, the IDE
3. Whenever the ToolStick adapter is directly connected to the key fob design platform and the IDE is con-
4. It is recommended that the user uses the Programming board along with the USB Debug Adapter.
a boot sequence.
issues a system reset and the device reboots. The content of the RAM memories is not touched by the
boot, with the exception of the API reserved regions in CODE/XDATA and DATA/IDATA memories. The
register banks RB0, RB1, and RB3 are cleared by the boot routine.
necting to the part, the GPIO0 will be forcibly driven to 1 for about 260 ms around the beginning of the con-
nection sequence. In the Silicon Labs-provided key fob platform, the GPIO0 isolated by a resistor, then if
the user is pressing a GPIO0 button during the connection sequence, the GPIO0 value will be viewed as 1
by the internal CPU during the IDE connection to the device.
