(2) Write to internal verify
Note Perform processing to shift to normal mode in order to return to normal processing.
Remark
<1> Mode is shifted from normal mode to self programming mode (<1> to <7> in 14.8.4)
<2> Specification of source data for write
<3> Execution of byte write
<4> <3> is repeated until all data are written.
<5> Execution of internal verify
<6> Mode is shifted from self programming mode to normal mode (<1> to <6> in 14.8.5)
