11.2.16 Octal Word Read Quad I/O (E3h)
The Octal Word Read Quad I/O (E3h) instruction is similar to the Fast Read Quad I/O (EBh) instruction
except that the lower four Address bits (A0, A1, A2, A3) must equal 0. As a result, the four dummy clocks
are not required, which further reduces the instruction overhead allowing even faster random access for
code execution (XIP). The Quad Enable bit (QE) of Status Register-2 must be set to enable the Octal
Word Read Quad I/O Instruction.
Octal Word Read Quad I/O with “Continuous Read Mode”
The Octal Word Read Quad I/O instruction can further reduce instruction overhead through setting the
“Continuous Read Mode” bits (M7-0) after the input Address bits (A23-0), as shown in figure 15a. The
upper nibble of the (M7-4) controls the length of the next Octal Word Read Quad I/O instruction through
the inclusion or exclusion of the first byte instruction code. The lower nibble bits of the (M3-0) are don’t
care (“x”). However, the IO pins should be high-impedance prior to the falling edge of the first data out
clock.
If the “Continuous Read Mode” bits (M7-0) equals “Ax” hex, then the next Octal Word Read Quad I/O
instruction (after /CS is raised and then lowered) does not require the E3h instruction code, as shown in
figure 15b. This reduces the instruction sequence by eight clocks and allows the Read address to be
immediately entered after /CS is asserted low. If the “Continuous Read Mode” bits (M7-0) are any value
other than “Ax” hex, the next instruction (after /CS is raised and then lowered) requires the first byte
instruction code, thus returning to normal operation. A “Continuous Read Mode” Reset instruction can be
used to reset (M7-0) before issuing normal instructions (See 11.2.32 for detailed descriptions).
