7.8 4-Wire Serial Port Interface
The SPI interface is used as interface between the AS8510 and an external micro-controller to configure the device and access the status
information. The micro-controller begins communication with the SPI which is configured as a slave. The SPI protocol is simple and the length of
each frame is an integer multiple of bytes except when a transmission is started. Each frame has 1 command bit, 7 address/configuration bits,
and one or more data bytes. The edge of CS and the level of SCLK during the start of a SPI transaction, determine the edge on which the data is
transferred from the SPI and the edge on which the data is sampled by the slave. Table 29 describes the setting of the transfer and sampling
edges of SCLK. Figure 9 shows the falling edge and rising edge for data transfer and data sampling respectively, when SCLK is HIGH on the
falling edge of CS.

7.8.1 SPI Frame
A frame is formed by a first byte for command and address/configuration and a following bit stream that can be formed by an integer number of
bytes. Command is coded on the 1 first bit, while address is given on LSB 7 bits (see Table 30).
If the command is read or write, one or more bytes follow. When the micro-controller sends more bytes (keeping CS LOW and SCLK toggling),
the SPI interface increments the address of the previous data byte and writes/reads data to/from consecutive addresses.
