Specifications
Maximum Offset G_max,
G_max = (65535 - C₀₎ / 1800
= (65535 - 32767) / 1800
= 18.20
Gain Error G_r,
G_r = (G_max - G₀) / G₀ * 100%
= (18.20 - 13.65) / 13.65 * 100%
= 33%
3.12 Bluetooth Accelerator
IMPORTANT:
On-chip accelerator hardware is not supported by software. An external
Bluetooth chip interfaced to a UART is recommended.
The Bluetooth Accelerator (BTA) radio interface supports the Motorola Radio, MC13180 using an SPI interface.
This section provides the data bus timing diagrams and SPI interface timing diagrams shown in Figure 38 and
Figure 39 on page 59, and the associated parameters shown in Table 24 and Table 25 on page 59.
