Figure 6: Block Erase Command Sequence
10.7 Erase Suspend / Resume
The Erase Suspend command interrupts the Block Erase to read or program data in a block that is not being erased. The Erase Suspend command is
only valid during the Block Erase operation including the time window of 50us. The Erase Suspend command is not valid while the Chip Erase or the
Internal Program Routine sequence is running.
When the Erase Suspend command is written during a Block Erase operation, the device requires a maximum of 20us to suspend the erase operation.
But, when the Erase Suspend command is written during the block erase time window (50us) , the device immediately terminates the block erase time
window and suspends the erase operation.
After the erase operation has been suspended, the device is availble for reading or programming data in a block that is not being erased. The system may
also write the autoselect command sequence when the device is in the Erase Suspend mode.
When the Erase Resume command is executed, the Block Erase operation will resume. When the Erase Suspend or Erase Resume command is exe-
cuted, the addresses are in don't care state. While erase can be suspended and resumed multiple times, a minimum 30us is required from resume to the next
suspend.
In the erase suspend mode, protect/unprotect command is prohibited.

10.8 Program Suspend / Resume
The Program Suspend command interrupts the Program operation. Also the Program Suspend command interrupts the Program operation during Erase
Suspend Mode. The Read operation is available only during Program Suspend. When the Program Suspend command is written during a Program oper-
ation, the device requires a maximum of 10us to suspend the Program operation. The system may also write the autoselect command sequence when
the device is in the Program Suspend mode. When the Program Resume command is executed, the Program operation will resume. When the Program
Suspend or Program Resume command is executed, the addresses are in don't care state. While program can be suspended and resumed multiple
times, a minimum 30us is required from resume to the next suspend.
In the program suspend mode, protect/unprotect command is prohibited.
