Name Description Comment
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).
