3.7 READ
The READ instruction outputs the serial data of the
addressed memory location on the DO pin. A dummy
zero bit precedes the 8-bit (If ORG pin is low or A-version
devices) or 16-bit (If ORG pin is high or B-version
devices) output string. The output data bits will toggle on
the rising edge of the CLK and are stable after the spec-
ified time delay (TPD). Sequential read is possible when
CS is held high. The memory data will automatically cycle
to the next register and output sequentially.
