4.2.12.1. General Description

As illustrated in Figure 29, in Continuous mode the NRZ data to (from) the (de)modulator is directly accessed by the uC on

the bidirectional DIO2/DATA pin. The FIFO and packet handler are thus inactive.

4.2.12.2. Tx Processing

In Tx mode, a synchronous data clock for an external uC is provided on DIO1/DCLK pin. Clock timing with respect to the

data is illustrated in Figure 30. DATA is internally sampled on the rising edge of DCLK so the uC can change logic state

anytime outside the grayed out setup/hold zone.

Note

the use of DCLK is required when the modulation shaping is enabled (see section 3.4.5).
