A12:A9

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

program max latency =(count+1)*units

units (00b:128ns, 01b:1µs, 10b:8µs, 11b:64µs)

A17:A13= count = 24 = 11000b

Erase Resume to Suspend Interval

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

erase operation before allowing another suspend.

Interval = 500µs

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