5.3. Continuous Mode

5.3.1. General Description

As illustrated in Figure 34, in Continuous mode the NRZ data to (from) the (de)modulator is directly accessed by

the uC on the bidirectional DATA pin (20). The SPI Data, FIFO and packet handler are thus inactive.

5.3.2. Tx Processing

In Tx mode, a synchronous data clock for an external uC is provided on IRQ_1 pin. Its timing with respect to the

data is illustrated in Figure 35. DATA is internally sampled on the rising edge of DCLK so the uC can change logic

state anytime outside the greyed out setup/hold zone.

The use of DCLK is compulsory in FSK and optional in OOK.
