7.3 COMMUNICATION PROTOCOL

The WTS701 is controlled by a series of SPI transactions to send commands to the device. The

general format of an SPI transaction is shown in Figure 9. A transaction is always started by sending a

command word. The command word consists of a command byte followed by a command data byte.

At the same time, the status register is shifted out on the MISO line. What follows depends on what

command is sent. The general case is that following the command word, up to n-bytes of data can be

sent to the device and n-bytes can be read from the device. An SPI transaction is finished when SS

is returned to the HIGH condition.
