and a rising transition indicates the end of the operation. After CS is set
to low, a 5-bit instruction on SDI is input to the device on the rising edge
of SCLK. If the MSB is ‘1’, it is a read operation. If the MSB is ‘0’, it is a

write operation. Following the instruction, an 11-bit address is clocked in
on SDI to specify the register. If the device is in a read operation, the
data read from the specified register is output on SDO on the falling
edge of SCLK (refer to Figure-54). If the device is in a write operation,
the data written to the specified register is input on SDI following the
address byte (refer to Figure-55).
