with the microprocessor. A falling transition on CS pin indicates the start
of a read/write operation, and a rising transition indicates the end of the
operation. After the CS pin is set to low, two bytes include instruction
and address bytes on the SDI pin is input to the device on the rising
edge of the SCLK pin. First byte consists of one instruction bit at MSB
and three address bits at LSB, the second byte is low 8 address bits. If
the MSB is ‘1’, it is read operation. If the MSB is ‘0’, it is write operation.
If the device is in read operation, the data read from the specified regis-
ter is output on the SDO pin on the falling edge of the SCLK (refer to
Figure 39). If the device is in write operation, the data written to the
specified register is input on the SDI pin following the address byte (refer
to Figure 40).
