The time taken by the AT2LP to access the drive after reset is programmable and depends on an EEPROM byte setting. The Delay after Reset configuration at address 0x0D, determines the time taken. Default value of 0x00 would cause a delay of 1000ms before the AT2LP accesses the drive. Any other value would give corresponding increment as a multiple of 20ms.
More about the configuration setting can be obtained from the datasheet of AT2LP.
