5.4. Continuous Mode
5.4.1. 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.
5.4.2. 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.
