7.1 Overview
The following figure shows the MKW01Z128 data processing circuit. Its role is to interface the data
to/from the modulator/demodulator and the MCU access points (SPI and DIO pins). It also controls all the
configuration registers.
The circuit contains several control blocks which are described in the following paragraphs.
Figure 7-1. MKW01Z128 Data Processing Conceptual View
The MKW01Z128 implements several data operation modes, each with their own data path through the
data processing section. Depending on the data operation mode selected, some control blocks are active
whilst others remain disabled.
7.1.1 Data Operation Modes
The MKW01Z128 has two different data operation modes selectable by the user:
• Continuous mode: each bit transmitted or received is accessed in real time at the DIO2/DATA pin.
This mode may be used if adequate external signal processing is available.
