If the bit synchronizer is disabled, the raw demodulator output is made directly available on DATA pin and no DCLK
signal is provided.
Conversely, if the bit synchronizer is enabled, synchronous cleaned data and clock are made available respectively
on DATA and IRQ_1 pins. DATA is sampled on the rising edge of DCLK and updated on the falling edge as
illustrated in Figure 28.
Note that in Continuous mode it is always recommended to enable the bit synchronizer to clean the DATA signal
even if the DCLK signal is not used by the uC. (bit synchronizer is automatically enabled in Buffered and Packet
mode).
The tables below give the description of the interrupts available in Continuous mode.

Note: In Continuous mode, no interrupt is available in Stby mode
