Addresses 0000H and 0001H
Vector table wherein the program start address and the values set for the RBE and MBE at the time a RESET
signal is generated are written. Reset start is possible from any address.
Addresses 0002H to 000DH
Vector table wherein the program start address and the values set for the RBE and MBE by each vectored
interrupt are written. Interrupt processing can start from any address.
Addresses 0020H to 007FH
Table area referenced by the GETI instructionNote.
Note
The GETI instruction realizes a 1-byte instruction on behalf of any 2-byte instruction, 3-byte
instruction, or two 1-byte instructions. It is used to decrease the number of program steps.
