CE Bus Connector
V200 Personal Communicators have the Motorola CE Bus interface.
The bus incorporates RS232 serial communication and universal serial bus (USB)
into one connector.
The CE Bus supports connection to accessories, personal computers, and test
systems. The bus connector has a total of 17 pins, 9 of which have multiple functions.
For signal name and function details, refer to Table 27 in this manual and the
V200Level 3 Supplement listed in the Related Publication section,
later in this manual.
The bus has six basic modes of operation:
• Normal (also No Accessory Connected),
• USB Mode,
• Analog Audio Mode,
• Phone Powered USB Mode,
• RS-232 Mode, and
• RS-232/SSI Mode.
There are also three additional non-standard modes, DSC, FLASH, and JTAG,
which are used only for development, factory programming, and debugging.
Eight of the 17 pins have different functions depending on which mode is selected.
The other nine pins always have the same function regardless of mode. The mode
is selected by applying appropriate logic levels to the Option Select pins, named
OPTION1 and OPTION2. Some of the modes listed above are selected by the
additional application of a level on the USB POWER and AUDIO-IN pins as well.
