Does anyone have information for pins 5 and 6 - SOUT and VTOUCH? What is their purpose and how are they used?Thanks

The Adafruit library has limitations, (Adafruit_Fingerprint.cpp) in the fingerFastSearch method the search requestion has as parameters the pageStart and pageEnd, however they are limited 0x00 ~ 0xFF. Thus, the search does not cover all registered biometrics.
