4.11 Jumper Selection
Table 4-6 lists all the possible jumper selections for the 1320x-QE128EVB. The jumpers available on the
board include:
• J1 - used to measure current and voltage on V_RF
• J5 - used to select clock input to the MCU either from the MC1320x CLKO output or from an
optional on-board (Y2) 32.768KHz crystal.
• J6 - used to measure current and voltage on V_BB
• J13 - used to connect MCU TxD1 pin to the on-board RS-232 transceiver (U5)
• J15 - used to connect MCU RxD1 pin to the on-board RS-232 transceiver (U5)
