Table 31. Description of PCRx bits
Bit Symbol Description
7 PCR7 not used
6 PCR6 not used
5C8 Contact 8 (C8). When writing to register PCR, pin C8 will output
the value of bit C8. When reading from register PCR, bit C8 will
store the value on pin C8
4C4 Contact 4 (C4). When writing to register PCR, pin C4 will output
the value of bit C4. When reading from register PCR, bit C4 will
store the value on pin C4.
31V8 1.8 V cards. If bit 1V8 is set, then V
CC
= 1.8 V: it should be
noted that no specification is guaranteed with this V
CC
voltage
when the supply voltage V
DD
is inferior to 3 V
2RSTIN Reset In (RSTIN). When the card is activated, pin RST is the
copy of the value written in bit RSTIN.
13V/5V 3Vor5V cards. If bit 3V/5V = 1, then V
CC
=3V; if
bit 3V/5V = 0, then V
CC
=5V.
0START Start. If the microcontroller sets bit START = 1, then the
selected card is activated (see Section 8.6
); if the
microcontroller resets bit START = 0, then the card is
deactivated (see Section 8.7). Bit START is automatically reset
in case of emergency deactivation. To deactivate the card, only
bit START should be reset.
