Functional Description and Application Information
4.6.4
Gain error calculations are made using the information in this section.
Assuming the offset remains unchanged, the mapping is rotated around y-intercept to determine the
maximum gain allowed. This occurs when the sample at 1800mV has just reached the ceiling of the 16-bit
range, 65535.

The Bluetooth Accelerator (BTA) radio interface supports the Wireless RF Transceiver, MC13180 using
an SPI interface. This section provides the data bus timing diagrams and SPI interface timing diagrams
