20 JP21 8010R
INT INT2 select Selects the source for INT2 between the
73S8010R and the OFF_REQ pin on the
73S1217F. Should be set opposite of JP9.
21 JP13 Not
Inserted Jumper: USR7/SDA
select This jumper selects which signal is connected to
the daughter board connector pin USR7:
•
In position “USR7”, the 73S1217F USR7
signal is connected to the daughter card pin
USR7.
•
In position “SDA”, the I2C SDA signal is
connected to the daughter card pin USR7.
This allows the SDA line to connect to an
SDA pin on a 73S8010R daughter card.
22 JP14 Not
Inserted Jumper: USR7/SDA
select This jumper allows the on board 73S8010R
AUX2 pin to be connected to USR5 if needed. If
not needed, the jumper should be removed.
23 U4 On board 73S8010R The board contains a built-in 73S8010R that is
connected to the external smart card interface of
the 73S1217F. This device can be
disconnected from the 73S1217F if not used, by
removing jumpers JP12 and JP21.
24 J7,J8 Optional 73S80xxX
Daughter Board
interface When developing applications that require more
than 2 smart card interfaces, an optional
daughter board can be populated to use the
73S1217F external smart card interface (lines
SCIO and SCK), in conjunction with the
USR(0:7) port and the INT2 interrupt input of the
73S1217F). Refer to the electrical schematic for
pin assignment.
25 J9, J10 SIM / SAM and Smart
Card connectors –
external interface (#2) Allows the evaluation board to communicate
with a smart card using either the standard
(credit card size) or SIM/SAM format. This slot
is connected to the 73S1217F external card
interface # 2.
Note that J10 is wired is parallel to the smart
card connector J9 (underneath the PCB). Both
connectors cannot be populated at the same
time.
26 JP11 Not
Inserted Jumper: USR6/SCL
select This jumper selects which signal is connected to
the daughter board connector pin USR6:
•
In position “USR6”, the 73S1217F USR6
signal is connected to the daughter card pin
USR6.
•
In position “SCL”, the I2C SCL signal is
connected to the daughter card pin USR6.
This allows the SCL line to connect to an SCL
pin on a 73S8010R daughter card.
27 JP10 Not
Inserted Jumper: USR6/AUX1
select This jumper allows the on board 73S8010R
AUX1 pin to be connected to USR6 if needed. If
not needed the jumper should be removed.
