(3) Description of symbols used in addressing area

Remarks 1. MB indicates access-enabled memory banks.

2. In area *2, MB = 0 for both MBE and MBS.

3. In areas *4 and *5, MB = 15 for both MBE and MBS.

4. Areas *6 to *11 indicate corresponding address-enabled areas.

MB = 0 (000H-07FH)

MB = 15 (F80H-FFFH)

MB = MBS

MBS = 0-3, 15

MB = MBE • MBS

MBS = 0-3, 15

MB = 0

MBE = 1

MBE = 0

MB = 15, fmem = FB0H-FBFH, FF0H-FFFH

MB = 15, pmem = FC0H-FFFH

addr = 0000H-3FFFH

addr, addr1 =

(Current PC) –15 to (Current PC) –1

(Current PC) +2 to (Current PC) +16

caddr = 0000H-0FFFH (PC14, 13, 12 = 000B) or

1000H-1FFFH (PC14, 13, 12 = 001B) or

2000H-2FFFH (PC14, 13, 12 = 010B) or

3000H-3FFFH (PC14, 13, 12 = 011B) or

4000H-4FFFH (PC14, 13, 12 = 100B: Mk II mode only) or

5000H-5FFFH (PC14, 13, 12 = 101B: Mk II mode only) or

6000H-6FFFH (PC14, 13, 12 = 110B: Mk II mode only) or

7000H-7F7FH (PC14, 13, 12 = 111B: Mk II mode only)

faddr = 0000H-07FFH

taddr = 0020H-007FH

addr1 = 0000H-7FFFH (Mk II mode only)
