Program/Erase Suspend
The Program/Erase Suspend instruction allows the controller to interrupt a Program or an
Erase instruction, in particular: Sector Erase and Quad Command Page Program can be
suspended and erased while that Subsector Erase, Bulk Erase, Write Non Volatile
Configuration register and Program OTP can not be suspended.
Apart form parallelizing the instruction code on four pins (DQ0, DQ1, DQ2, DQ3) the
instruction functionality is the same as the Program/Erase Suspend (PES) instruction of the
Extended SPI protocol. Refer to
Figure 113. Program/Erase Suspend instruction sequence QIO-SPI
Program/Erase Resume
After a Program/Erase suspend instruction, a Program/Erase Resume instruction is
required to continue performing the suspended Program or Erase sequence. Apart form
parallelizing the instruction code on four pins (DQ0, DQ1, DQ2, DQ3) the instruction
functionality is the same as the Program/Erase Resume (PER) instruction of the Extended
SPI protocol. Refer to
Figure 114. Program/Erase Resume instruction sequence QIO-SPI
