2) Read during reset phase
a) Program RAM read (during reset phase)
To read data written into PRAM, input the command code and the address you want to read out. After that, set SI to "H"
and SCLK to "L". Then the data is output from SO in synchronization with the falling edge of SCLK. (Ignore the RDY
operation that will occur in this case.)
If there are continuous addresses to be read, repeat the above procedure starting from the step where SI is set to "H".
