Modify a few resistor values relating to JTAG selection
R166 change from 10k to 4.7 kOhm R72 and R73 change from 1k to 47 kOhm Eliminates chance that U39 (PCAL9555A I2C port expander) can interfere with logic Does mean that anyone who wants to use U39 to sense EN_CON_JTAG_R or EN_USB_JTAG should disable the chip's internal pull-ups using configuration register 46h
