P14.6
HWCFG0 (LDO / DCDC)
Only with TC2X5, resistor R30 (4.7 kΩ/0603
imp) pulls signal against GND (DCDC) and is
assembled initially if board is using TC2X5.
P14.5
HWCFG1 (EVR33ON / EVR33OFF)
Resistor R31 (4.7 kΩ/0603 imp) pulls signal
against GND (EVR33OFF) and is assembled
initially.
P14.2
HWCFG2 (EVRCON / EVRCOFF)
Resistor R52 (4.7 kΩ/0603 imp) must be
assembled if R59 is assembled (GPIOs are set
to tri-state) and TC2X5 is used (TC3X5 has
internal pull-up).
P14.3
HWCFG3 (see boot configuration Table 6)

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