5. MEMORY CONFIGURATION
Program memory (ROM)
4096
×
8 bits
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 and start are possible at an arbitrary address.
Addresses 0002H to 000FH
Vector table wherein the program start address and values set for the RBE and MBE by the vectored interrupts
are written. Interrupt service can be started at an arbitrary address.
Addresses 0020H to 007FH
Table area referenced by the GETI instruction
Note
.
Note
The GETI instruction realizes a 1-byte instruction on behalf of an arbitrary 2-byte instruction, 3-byte
instruction, or two 1-byte instructions. It is used to decrease the program steps.
