Dual I/O Fast Read (BBH)

The Dual I/O Fast Read command is similar to the Dual Output Fast Read command but with the capability to input the

3-Byte address (A23-

0) and a “Continuous Read Mode” Byte 2-bit per clock by SI and SO, each bit being latched in during

the rising edge of SCLK, then the memory contents are shifted out 2-bit per clock cycle from SI and SO. The command

sequence is shown in followed Figure 9. The first Byte addressed can be at any location. The address is automatically

incremented to the next higher address after each Byte of data is shifted out.

Dual I/O Fast Read with “Continuous Read Mode”

The Dual I/O Fast

Read command can further reduce command overhead through setting the “Continuous Read Mode”

bits (M7-0) after the input 3-Byte address (A23-

A0). If the “Continuous Read Mode” bits (M7-0) =AXH, then the next Dual

I/O Fast Read command (after CS# is raised and then lowered) does not require the BBH command code. The command

sequence is shown in followed Figure 10

. If the “Continuous Read Mode” bits (M7-0) are any value other than AXH, the

next command requires the first BBH command code, thus returning to nor

mal operation. A “Continuous Read Mode” Reset

command can be used to reset (M7-0) before issuing normal command.
