Serial Interface

The S1V3G340 serial interface can be set to clock synchronous, asynchronous (UART), or I2C.
• Clock synchronous
Supports slave mode.
Data length: 8-bit, fixed, MSB first
• Asynchronous (UART)
Data length: 8-bit, fixed, LSB first
Start bit: 1-bit, fixed
Stop bit: 1-bit or 2-bit, selectable (default: 1-bit)
Parity bit: Even, odd, or none, selectable (default: none)
Baud rate [bps]: 460 k, 230 k, 115 k, 57.6 k, 38.4 k, 19.2 k, 9.6 k (default: 9.6 kbps)
• I2C
Supports I2C slave mode.
Maximum transfer speed: 83.3 kHz (when I2C bus rising time is 480 ns or less)
Serial interface selection is defined by the input pin SHISEL[1:0] settings.
Table 5.2 lists serial interface mode settings.
