Examples Of Operation When Command Execution Time Should Be Minimized In Self Programming Mode - NEC 78K0S/KU1+ User Manual

16.8.10 Examples of operation when command execution time should be minimized in self programming
mode
Examples of operation when the command execution time should be minimized in self programming mode are
explained below.
(1) Erasure to blank check
<1> Mode is shifted from normal mode to self programming mode (<1> to <7> in 16.8.4)
<2> Execution of block erase → Error check (<1> to <11> in 16.8.6)
<3> Execution of block blank check → Error check (<1> to <11> in 16.8.7)
<4> Mode is shifted from self programming mode to normal mode (<1> to <6> in 16.8.5)
