+02H | LINK specification/8H | 0 | 0 |
- CMDLINK: Command table start address +02H
- When the command table being processed is finished, if the jump format is Assign, the process moves to the command table at the CMDLINK address, and if it is a call, the command table at the CMDLINK address is called as a subroutine, and processing is transferred to the next command table to be processed. Migrate.
For the address, specify the VRAM address divided by 8H in 16 bits. The command table is stored in a boundary of 20H (32) bytes, so the lower 2 bits of CMDLINK are 00H.
This CMDLINK is ignored when the jump format (JP) specifies the next table or returns to the main routine.
