Error Bit (DQ5). The Error Bit can be used to
identify if an error occurs during a program or
erase operation.
The Error Bit is set to ‘1’ when a program or erase
operation has failed. When it is set to ‘0’ the pro-
gram or erase operation was successful.
If any Program command is used to try to set a bit
from ‘0’ to ‘1’ Status Register Error bit DQ5 will be
set to ‘1’, only if V
12.6V.
The Error Bit is reset by a Read/Reset command.
Erase Timer Bit (DQ3). The Erase Timer bit is
used to indicate the timeout period for an erase
operation.
When the last block Erase command has been en-
tered to the Command Interface and it is waiting
for the erase operation to start, the Erase Timer Bit
is set to ‘0’. When the erase timeout period is fin-
ished, DQ3 returns to ‘1’, (80µs to 120µs).
