1V8
Not used.
Select 1.8 V.
If 1V8 = 1, then V
CC
= 1.8 V. It should be noted that specifications are not
guaranteed at this voltage when the supply voltage V
DD
is less than 3 V.
Card reset.
When the card is activated, pin RST is the copy of the value written in
RSTIN.
Select 3 V or 5 V.
If 3V/5V = 1, then V
CC
= 3 V. If 3V/5V = 0, then V
CC
= 5 V.
Activate and deactivate card.
If START = 1 is written by the controller, then the card is
activated (see description of activation sequence in Section 8.16). If the controller writes
START = 0, then the card is deactivated (see description of deactivation sequence in
Section 8.17). START is automatically reset in case of emergency deactivation.
