1.6 Definitions
Asserted/Activated:
Asserted and activated mean that a signal is driven to its true state.
Block:
This term refers to the data in one logical block. The block size depends on the parameter of packet
command.
Block-Offset/Linear Address:
The block-offset address is an indirect mapping to the external RAM. The offset range is limited by
the block size. The linear address is a direct mapping to the external RAM.
Command Packet (CP):
The command packet is the structure used to communicate commands from a host computer to an
ATAPI device. All CD-ROM command packets are 12 bytes in length.
Data-in/Data-out Transfer:
During the data-in transfer, the data is transferred from device to host. During the data-out transfer,
the data is transferred from host to drive.
