The Read SFDP instruction is terminated by driving Chip Select (S) High at any time during
data output.
Any Read Serial Flash Discovery Parameter (RDSFDP) instruction issued while an Erase or
Program cycle is in progress, is rejected without having any effect on the cycle that is in
progress.

Dual Output Fast Read (DOFR)
The Dual Output Fast Read (DOFR) instruction is very similar to the Read Data Bytes at
Higher Speed (FAST_READ) instruction, except that the data are shifted out on two pins
(pin DQ0 and pin DQ1) instead of only one. Outputting the data on two pins instead of one
doubles the data transfer bandwidth compared to the Read Data Bytes at Higher Speed
(FAST_READ) instruction.
The device is first selected by driving Chip Select (S) Low. The instruction code for the Dual
Output Fast Read instruction is followed by a 3-byte address (A23-A0) and a configurable
number of dummy clock cycles, each bit being latched-in during the rising edge of Serial
Clock (C). Then the memory contents, at that address, are shifted out on DQ0 and DQ1 at a
maximum frequency Fc, during the falling edge of Serial Clock (C).
