2.
Not 100% tested.
See the
“Erase And Programming Performance”
section for more
information.
For 1–16 words/1–32 bytes programmed.
Effective write buffer specification is based upon a
16-word/32-byte write buffer operation.
Word/Byte programming specification is based upon a single
word/byte programming operation not utilizing the write buffer.

When using the program suspend/resume feature, if the suspend
command is issued within t
POLL
, t
POLL
must be fully re-applied
upon resuming the programming operation. If the suspend
command is issued after t
POLL
, t
POLL
is not required again prior to
reading the status bits upon resuming.
