Address Control
1. Address Control for Recording
The LSI is designed to make recording in sectors, as the minimum recording unit. When a user sets up the Starting
Address for recording by using the STADR command, the page address, lower 4-bit of 13-bit user-defined Starting
Address, is automatically set to “0H” internally. Thus recording always begins at the starting address of each
sectors.
Meanwhile, when you define the Stop Address for recording by using the SPADR command, full 13-bit address
definition is valid. This enables you to specify the Stop Address for recording in pages. However, within the LSI
recording continues as far as to the last address of the following sector.
If the RDADR command is used to read the address value of the Memory Address Counter after completion of
recording, output value represents the Memory Address Counter’s value either at the time when the Stop Address
defined by the SPADR command has been reached, or when the LSI receives the STOP command that causes the
LSI to stop recording.
2. Address Control for Playback
The LSI is designed to make playback in pages, as the minimum playback unit, so full 13-bit address definition is
valid both with the STADR command and the SPADR command. You can, therefore, specify the start and stop
location by unit of page.
