7-2-d) OFRAM data read (during reset phase)
The written offset data can be read out during the reset phase. To read it, input the command code and the address
you want to read. After that, set SI to "H" and SCLK to "L". This completes preparation for outputting the data. Then
set SI to "L", and the data is clocked out in synchronization with the falling edge of SCLK. If there are continuous
addresses to be read, repeat the above procedure starting from the step where SI is set to “H”.
