Program / Erase Resume
The Resume instruction must be written to resume the Sector
or Block Erase operation or the Page Program operation
after a Program/Erase Suspend. The Resume instruction will
be accepted by the device only if the SUS bit in the Status
Register equals to 1 and the WIP bit equals to 0. After issued
the SUS bit will be cleared from 1 to 0 immediately, the WIP
bit will be set from 0 to 1 within 200ns and the Sector or
Block will complete the erase operation or the page will
complete the program operation. If the SUS bit equals to 0 or
A25LQ32A Series
the WIP bit equals to 1, the Resume instruction will be
ignored by the device. The Resume instruction sequence is
shown in figure 30.
Resume instruction is ignored if the previous Program/Erase
Suspend operation was interrupted by unexpected power off.
It is also required that a subsequent Program/Erase Suspend
instruction not to be issued within a minimum of time of “tSUS”
following a previous Resume instruction.
