Auxiliary output and BEEP delay timing (if options are enabled)
Mifare card in field for first time, Auxiliary output enabled and BEEP delay set. Green LED
signal can be used as an interrupt signal to the host to indicate that auxiliary data will follow.

Summary of Polling rates and command timing
Three polling rates:
1) NO card and NO commands: Polling rate determined by Polling rate parameter in
RWD EEPROM (4mS to 8 seconds, default setting 260mS)
2) Card present but NO commands: 100ms polling delay between CTS pulses.
3) Command (and parameters) received: 10ms polling delay to next CTS pulse.
For lowest power consumption, the Polling rate parameter in EEPROM is typically set to a
long period (> 1 second). Auxiliary output (if enabled) occurs after Green LED signal and
before CTS.
Host communication software must be able to handle the three polling rates.
