Figure 6. Serial Data Transfer Format
(1) The first 2-BITs are for transmission only and this product must send '01'.(Others are not permitted.)
(2) The following 6-bit data specifies the slave device, which is connected to the SPI bus and has its own ID.
(3) The following 1-bit is a dummy bit, which marks the end of the 8-bit data transmission and the beginning of
the next data to be sent.
(4) The following 1-bit decides on whether the master will drive the data line or the slave will. If this bit is '1', the
master will drive , but if '0' the slave will drive the data line.
(5) The following 7-bit data is the register address of the specified slave device; the 7-bits for an address allows
128 register addresses for slaves.
(6) The following high 1-BIT data is a dummy data.
(7) The following 8-BIT data is the data in the device to be driven.
(8) The following 1-BIT data is a dummy data, which marks the end of the 8-bit data transmission and
beginning of the next data to be sent.
(9) The following 1-bit decides on whether the master will drive the data line or the slave will. If this bit is '1', the
master will drive , but if '0' the slave will drive the data line.
(10) The following 7-bit data is the register address of the specified slave device.
(11) The following high 1-BIT data is a dummy data.
(12) The following 8-BIT data is the data in the device to be driven.
(Continous data transmission such as this can be ended with a 1-byte transmission or can be read/written
repeatedly.)
(13) After the last data is sent, the data line opens and becomes high;
(14) the CLK continues for half the 1-clock cycle and then becomes high;
(15) and the STB becomes high as soon as the clock becomes high and this marks the end of data transmission.
