Jumper Descriptions

TWR-K60N512 Jumpers

The jumpers used to configure the MCBTWRK60 TWR-K60N512 board are:

• J1: connects USB power from the Primary Elevator to the VREGIN on the board.
• J2: connects the IR transmitter to PTD7/CMT_IRO/UART0_TX.
• J6: jumpering the 1-2 position selects the on-board 50 MHz clock. Jumpering the 2-3 position uses a clock signal from the Primary Elevator board.
• J8: connects the on-board power supply to the MCU.
• J9: jumpering 1-2 connects the on-board power supply to VBAT. Jumpering 2-3 connects VBAT to the coin-cell battery.
• J10: selects OSJTAG bootloader mode for OSJTAG reprogramming.
• J12: connects 5 VDC to the JTAG port.
