5. MEMORY CONFIGURATION

• Program memory (ROM) : 4,096 × 8 bits (0000H-0FFFH): µPD750104

6,144 × 8 bits (0000H-17FFH): µPD750106

8,192 × 8 bits (0000H-1FFFH): µPD750108

• 0000H to 0001H

Vector address table for holding the RBE and MBE values and program start address when a RESET signal is

issued (allowing a reset start at an arbitrary address)

• 0002H to 000DH

Vector address table for holding the RBE and MBE values and program start address for each vectored interrupt

(allowing interrupt processing to be started at an arbitrary address)

• 0020H to 007FH

Table area referenced by the GETI instructionNote

Note The GETI instruction requires only one byte to represent an arbitrary two-byte or three-byte instruction or

two one-byte instructions, reducing the number of program bytes.

• Data memory (RAM)

• Data area

: 512 × 4 bits (000H to 1FFH)

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