Program Operation Flow Diagram
NOTE :
1) DBS must be set before data input.
2) Data input could be done anywhere between "Start" and "Write Program Command".
3) ‘Write 0 to interrupt register’ step may be ignored when using INT auto mode. Refer to chapter 2.8.18.1
During the execution of the Internal Program Routine, the host is not required to provide any further controls or timings. Furthermore, all com-
mands, except a Reset command, will be ignored. A reset during a program operation will cause data corruption at the corresponding location.
If a program error is detected at the completion of the Internal Program Routine, map out the block, including the page in error, and copy the
target data to another block. An error is signaled if DQ10 = "1" of Controller Status Register(F240h) .
Data input from the Host to the DataRAM can be done at any time during the Internal Program Routine after "Start" but before the "Write Pro-
gram Command" is written.
