Introduction

In response to customer requests, Cypress reduced many delays in the time between reset and startup for the AT2LP chip. The delay reduction occurred when the AT2LP went from revision B to revision C. With this timing change, certain drives (in many cases ATAPI drives) hang the host during the boot up process or during a soft reset [Ctrl] [Alt] [Del].
