Read (33 MHz)
The Read instruction, 03H, supports up to 33 MHz Read. The device outputs the data starting from the
specified address location. The data output stream is continuous through all addresses until termi-
nated by a low to high transition on CE#. The internal address pointer will automatically increment until
the highest memory address is reached. Once the highest memory address is reached, the address
pointer will automatically increment to the beginning (wrap-around) of the address space. Once the
data from address location 3FFFFH has been read, the next output will be from address location
000000H.
The Read instruction is initiated by executing an 8-bit command, 03H, followed by address bits [A
