Note:
 Unused pins remain floating. All GND pins are connected to the ground network.
 A single keyout/OUT button can not be used and needs to be used in conjunction with
KEYOUT/IN.
 When USB_BOOT/KEY_IN0 pin and KEYOUT are used as key function in combination, if the
corresponding key is pressed during power-on, the module will enter download mode because
KEYOUT has high pulse output during power-on.
 L610-CN-31/32 does not support KEYIN4/KEYIN5
