Function: It returns a byte, showing the status of the four digital inputs (0 to 3). If the bit
is at 0, the input is in open circuit. If the bit is at 1, the input is shorted to GND.
If bit 4 of the
CFG-DB_ECHO
is enabled (see
), the FingerVein VIM can
notify of the change in the digital input status via an event with the same OpCode.
