The VCC host power sequencing is non preferential;
however, VCC must be higher or equal to VCC1 and VCC2.
The Enable pin must be LOW while VCC1 and VCC2 ramp
up to valid supply voltages or ramp down to 0V.
A pull-up resistor tying enable to ground should be used
to ensure that bus contention, excessive currents, or
oscillations do not occur during power up or power
down. The size of the pull-up resistor is based upon the
current sinking capability of the device driving the
Enable pin.
Recommended power-up sequence (see Figure 16):
1.
Apply power to VCC.
2.
Assert EN LOW (FXLA2203 disabled).
3.
Apply power to VCC1, VCC2, VCC_H_1, and
VCC_H_2.
4.
Assert EN HIGH (FXLA2203 enabled).
5.
Begin activation timing (see Figure 14).
Recommended power-down sequence (see Figure 17):
1. Complete deactivation timing (see Figure 15).
2. Assert EN LOW (FXLA2203 disabled).
3. Ramp down power to VCC1, VCC2, VCC_H_1,
and VCC_H_2.
4. Once VCC1 and VCC2 are OFF, ramp down VCC.

Notes:
23. A=VCC becomes a valid voltage, EN=LOW.
24. B=VCC1, VCC2, and VCC_H_n become valid
voltages, EN=LOW.
25. C=FXLA2203 enabled (EN goes HIGH), ready for
activation (ISO7816-3).
Notes:
26. A=Disable FXLA2203, bring EN LOW.
27. B=Ramp down VCC1, VCC2, and VCC_H_n.
28. C=Ramp down VCC once VCC1 and VCC2 are off.
