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 = 500 µs

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

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 = 25 µs

program max. latency =(count+1)*units

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

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 = 500 µs

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