DESCRIPTION
START/STOP
0
when set, initiates an activation and a cold reset procedure; when reset, initiates a
deactivation sequence
when set, initiates a warm reset procedure; automatically reset by hardware when the card
starts answering or when the card is declared mute
when set, V
CC
= 3 V; when reset, V
CC
= 5 V
when set, the configuration defined by bit CLKPD is applied on pin CLK, and the circuit
enters the Power-down mode; when reset, the circuit goes back to normal (active) mode
when set, CLK is stopped HIGH during Power-down mode; when reset, CLK is stopped LOW
in Power-down mode
bits 5 and 6 determine the clock to the card in normal mode according to Table 3

when set, I/O is transferred on I/OuC; when reset, I/O to I/OuC is high-impedance
When deactivating the card, by resetting the START bit,
only bit 0 must be changed.
The clock to the cards in active mode is selected with
bits CLKSEL1 and CLKSEL2; see Table 3.
Table 3
Selecting the card clock.
All frequency changes are synchronous, thus ensuring
that no pulse is shorter than 45% of the smallest period.
For cards power reduction modes, CLKIN may be stopped
after switching to STOP LOW or STOP HIGH. CLKIN
should be restarted before leaving this mode.
A correct duty factor can not be guaranteed in the CLKIN
configuration, as it depends on the duty factor of the
CLKIN signal.
