The write sequence is as follows:
1. START condition
2. Byte 1: ADDRESS plus write command
3. ACK: acknowledge
4. Byte 2: CONTROL byte; see Table 3
5. ACK: acknowledge
6. STOP condition.
Table 3 CONTROL byte bits (all bits cleared after power-on)
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 and the selected frequency must not be changed during a CLK stop mode.
A correct duty factor can not be guaranteed in the CLKIN configuration, as it depends on the duty factor of the CLKIN
signal.

sequence
when set, initiates a warm reset procedure; automatically reset by hardware when the card starts
answering or when the card is declared mute (once the status has been read)
when set; V
when set, the configuration defined by bit CLKPD is applied to 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
determine the clock to the card in active mode:
when set, I/O data is transferred on pin I/OuC; when reset, pin I/OuC is high-impedance
