Appendix F Enabling UART, JTAG and 32.768 kHz Crystal
F.1
UART (2-wire), JTAG, and 32.768 kHz Crystal
In this configuration, the 2-wire UART, JTAG, 32.768 kHz crystal, and reset are applied. No cables
are required because the signal assignment is done on the PRO-DB with proper resistor mounting. In
PRO-MB, the appropriate jumper setting is applied on J1.
