Manage GPO
On receiving the Manage GPO command. Depending on the command argument, the
ST25DV force the GPO output level if RF_USER interrupt is enabled, or send a pulse on
GPO output if RF_INTERRUPT is enabled. If neither RF_USER nor RF_INTERRUPT was
enabled, the command is not executed and ST25DVxxx responds an Error code “0F”.
The IT duration is defined by IT_TIME register and occurs just after the command response.
For the ST25DVxx-JF (CMOS output), a set means that the GPO pin is driven to a High
level (VDCG) and a Reset pulls the GPO pin to a low level (VSS).
The IT corresponds to a transmission of a positive pulse on the GPO pin.
