On ASK LoGO hardware:
LEDs port bits definition:
* LED 1: bit 2 (P32)
* LED 2: bit 1 (P31)
* LED 3: bit 0 or 3 (depending of hardware revision) (P30 or P33)
* LED 4: bit 5 (P35)
Notes:
* Set logical 0 to switch LED on; logical 1 to switch LED off.
* Bit 4 should be maintained at 1 to keep RF field on.
Progressive field activation:
The ASK LoGO hardware can progressively power-up the antenna.
To use this feature we have to switch on the field by switching on
the field on PN533 (RFConfiguration) then set P34 to '1', and cut-off the
field by switching off the field on PN533 then set P34 to '0'.
