Program Resume to Suspend Interval

The device requires this typical amount of time to make progress on the

program operation before allowing another suspend.

Interval =500µs

Program resume to suspend interval =(count+1)*64µs

A12:A9= 7 =0111b

A15:A13

Suspend in-progress program max latency

Maximum time required by the flash device to suspend an in-progress

program and be ready to accept another command which accesses the

flash array.

Max latency = 25µs
