3.3 Strapping Pins
At each startup or reset, the WT0132C6-S5 and WT0132C6-S5U modules requires some initial configuration parameters, such as in which boot mode to load the chip, etc. These parameters are passed over via the strapping pins. After reset, the strapping pins operate
10
Wireless-Tag Technology Co., Limited
as regular IO pins. The parameters controlled by the given strapping pins at
chip reset are as follows:
V1.0.2
·SDIO input sampling and output driving clock edge MTMS and MTDI
·Chip boot mode GPIO8 and GPIO9
2
·ROM code printing GPIO8
·JTAG signal source GPIO15
GPIO9 is connected to the chip’s internal weak pull-up resistor at chip reset. This resistor determines the default bit value of GPIO9. Also, the resistor determines the bit value if GPIO9 is connected to an external high-impedance circuit.

IMPORTANT NOTES
Co-location warning: This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. OEM integration instructions: This device is intended only for OEM integrators under the following conditions:
The transmitter module may not be co-located with any other transmitter or antenna. The module shall be only used with the external antenna(s) that has been originally tested and certified with this module. As long as the conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
Validity of using the module certification: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
End product labeling: The final end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID: 2AFOS-WT0132C6-S5″ .
Information that must be placed in the end user manual: The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
