Read command
Input command code 0016 in the first transfer. Proceed and input the
low-order 8 bits and the high-order 8 bits of the address and pull the
__
OE pin low. When this is done, the M37754FFCGP and the
M37754FFCHP read out the contents of the specified address, and
__
then latch it into the internal data latch. When the OE pin is released
back high and serial clock is input to the SCLK pin, the read data that
has been latched into the data latch is serially output from the SDA
pin.

Note : When outputting the read data, the SDA pin is switched for output at the first falling edge of SCLK. The SDA pin is placed
in the floating state during the period of th(C-E) after the last rising edge of SCLK (at the 8th bit).
