NEC => Renesas Technology 

µPD754202, 754202(A)

5. MEMORY CONFIGURATION

• Program Memory (ROM): 2048 × 8 bits (0000H-07FFH)

• 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 values set for the RBE and MBE by the vectored interrupts

are written. Interrupt service 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.

• Data Memory (RAM)

• Data area: 128 words × 4 bits (000H-07FH)

• Peripheral hardware area: 128 words × 4 bits (F80H-FFFH)
