13.1 Description
The SPI is deselected. The MC33696 receives the message to transmit on the MOSI line (see
In OOK modulation (MODU=0), modulation is performed by switching the RF output stage on and off.
In FSK modulation (MODU = 1), modulation is performed by switching the RF carrier between two
values.
