P5 Jumpers - Texas Instruments Chipcon CC2430DB User Manual

The jumper between pin 3-4 can be removed when performing current measurement to
reduce leakage current of the peripheral devices connected to the CC2430. The jumper must
be mounted for normal operation
The jumper between pin 5-6 can be mounted to perform accelerometer self test function. By
mounting this jumper, a voltage is applied to the accelerometer outputs. See the Analog
Devices ADXL321 datasheet for details about the accelerometer self test. The jumper must
be removed for normal operation.

5.9.2 P5 Jumpers

All jumpers on header P5 must be mounted for normal operation.
The jumper between pin 1-2 on P5 connects DD (Debug Data) between USB MCU and
CC2430.
The jumper between pin 3-4 on P5 connects DC (Debug Clock) between USB MCU and
CC2430DB.
When the CC2430DB is used with emulator connected to the USB port, both the DD and DC
jumpers must be mounted. They should only be removed if an external emulator is used.
Chapter 6.2 gives instructions on how to connect the external emulator to the CC2430DB.
The jumper between pin 5-6 on P5 connects RESET_N signal between USB MCU and
CC2430. The jumper can be removed when performing current measurement to reduce
leakage current for the circuits connected to the RESET pin. The jumper must be mounted for
normal operation.
