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 Figure11. 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 normal operation. A “Continuous
Read Mode” Reset command can be used to reset (M7-0) before issuing normal command.
