38H

Suspend in-progress erase max. latency

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

and be ready to accept another command which accesses the Flash array.

Max. latency = 25 µs

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

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

A28:A24= count = 24 = 11000b

A30:A29 = 1 µs = 01b
