Notes:
1. The 32-kHz crystal signals are active in all modes.
The RESET signal is enabled as an input in all modes to reset the whole chip.
The BBATSEN signal is active during reset to sense the state of the backup battery.
Summary: No pullups or pulldowns on these pins.
2. The LF_VID signal is not supported on the ÉlanSC410 microcontroller.
