Notes
1. Sleep mode, that is with tx and rx not enabled
2. 1 Hz = 2 bps
3. The data slicer is optimised for a 50:50 duty cycle hence for reliable communications data
should be encoded using a suitable scheme such as Manchester Encoding, although pulse
width modulation up to 70:30/30:70 can also be used.
