Status Register (Cache program operation)
The status is output by writing 70h command in cache program / 2 page cache program operation.
I/O1, 2 which shows pass/fail and I/O6, 7 which shows Ready/Busy is output OR data of 2 page address
which programs simultaneously. In other words, if either 2 page address is Busy status, I/O6 or I/O7
outputs “0”. If either 2 page address fails, I/O1 or I/O2 outputs “1”.
It verifies the status writing 70h command in cache program operation and verification of detail error code
which page address fails in program is executed by writing 73h-76h command which output error content
corresponding to bank address.
It can also verify the status writing 70h in 2 page cache program operation and if either 2 page address
which programs simultaneously fails with program error, it outputs fail status. We recommend verifying
page address writing 71h command.
If error occurs in (N-1) page address, error management of (N-1) page (taking the data to replacement page
address) address needs to be executed after program completion of N page address.
