The setting of these two jumpers depends on the
type of smart card connector used (whether switch
is nominally open or closed), and which of the card
presence switch input of the 73S8009C is used. In
this demo board, the switch is nominally open. The
jumpers can be set in one of two ways:
Note: see board errata in the appendix for JP6
When inserting a card (credit card size format),
contacts must face up.
CS Disable Jumper. Insertion of jumper disables
the 73S8009CN. The state of the CMDVCC#,
CMDVCC% and RSTIN inputs will be latched and
the I/OUC, AUX1UC and AUX2UC are tri-stated.
The OFF and RDY outputs are also tri-stated.
Test point to monitor the internal intermediate
voltage regulator. This regulator output takes the
VPC voltage and step it up to more than 5 V (if
necessary) as the input source for the VCC and
VDD output regulators.
Connector that supplies the VPC input supply
voltage, the smart card data interface signals and
the OFF interrupt output.
Smart card connector.
1. Default setting: Use of PRES: JP5 must be
2. Alternative use: Use of PRES: JP5 must be
set to PRES, and JP6 set to VDD
set to PREB, and JP6 set to GND
