When writing to the MAX5893, data is shifted into SDI;
data is shifted out of SDO in a read operation. Bits 0 to
3 of the control byte are the address bits. These bits set
the address of the register to be written to or read from.
Bits 4 to 6 of the control byte must always be set to 0.
Bit 7 is a read/write bit: 0 for write operation and 1 for
read operation. The most significant bit (MSB) is shifted
in first in default mode. If the serial port is set to LSB-
first mode, both the control byte and data byte are shifted
LSB in first. Figures 1 and 2 show the SPI serial interface
operation in the default write and read mode, respectively.
Figure 3 is a timing diagram for the SPI serial interface.
