CS5460A  
4.1 Commands (Write Only)  
All command words are 1 byte in length. Commands that write to a register must be followed by 3 bytes of register  
data. Commands that read from registers initiate the output of 3 bytes of register data. Commands that read data  
can be ‘chained’ with other commands (e.g., while reading data, a new command can be sent to SDI which can ex-  
ecute before the original read is completed). This allows for ‘chaining’ commands.

This command indicates to the state machine to begin acquiring measurements and calculating results. The device  
has two modes of acquisition.  
Modes of acquisition/measurement  
0 = Perform a single computation cycle  
1 = Perform continuous computation cycles

This command is the end of the serial port re-initialization sequence. It can also be used as a NOP command. The  
serial port is resynchronized to byte boundaries by sending three or more consecutive SYNC1 commands followed  
by a SYNC0 command.

If the device is powered-down into either stand-by or sleep power saving mode (See 4.1.5), this command will pow-  
er-up the device. After the CS5460A is initially powered-on, no conversions/computations will be running. If the de-  
vice is already powered on and the device is running either ‘single computation cycle’ or ‘continuous computation  
cycles’ data acquisition modes, all computations will be halted once this command is received.
