P14.6
HWCFG0 (LDO / DCDC)
Only with TC234, resistor R30 (4.7 kΩ/0603 imp) pulls
signal against GND (DCDC) and is assembled initially
if board is using TC234.
P14.5
HWCFG1 (EVR33ON / EVR33OFF)
Only with TC3X4, resistor R31 (4.7 kΩ/0603 imp) pulls
signal against GND (EVR33OFF) and is assembled
initially.
P14.2
HWCFG2 (EVRCON / EVRCOFF for TC3X4)
HWCFG2 (EVR13ON / EVR13OFF for TC2X4)
Resistor R52 (4.7 kΩ/0603 imp) must be assembled if
R59 is assembled (GPIOs are set to tri-state).

P14.4
HWCFG6 (GPIOs pull-up / tri-state)
Only with TC3X4, resistor R59 (4.7 kΩ/0603 imp) pulls
signal against GND (GPIOs in tri-state after reset) and
and is not assembled initially.
