FTF 1100 MF1 V2.0 databook 3.3 (05.00)
3.2 EPP Register Definitions
The PC printer port uses five I/O addresses in EPP mode. As the EPP can emulate an
SPP the first three addresses 0,1 and 2 (offset to the base_address of the printer port, for
example 378h for LPT1) are used by SPP. The addresses 3 and 4 are used by the EPP.
As the FingerTIP only supports read cycles, address 4 is needed. By executing a single
I/O read instruction on [base_address + 4], the PC EPP controller will generate the
necessary handshake signals to transfer one data byte from the sensor to the PC. For
more information please refer to the Design-In Guideline /2/.
3.3 EPP 1.9 Signal Definitions
Table 2 describes the EPP signals and shows their corresponding SPP signals used by
the FingerTIP.

Table 2: Signal Definition of the FingerTIP (FTIP) in EPP 1.9 Mode
Table 3 shows the EPP pin names and the connection between the FingerTIP and the
printer port. Note that a one by one connection of the sensor and the printer port is not
recommended. Some PCs use weak output drivers for the handshake lines. This results in
poor signal quality if long cables are used between sensor and printer port. For more
information please refer to the Design-In Guideline /2/.
