3.3.2 ROM Addressing
ROM addressing specifies addressing of program variables in ROM space. The modes
provided are immediate addressing, table data addressing, and program code address-
ing.
[1]
Immediate Addressing
Immediate addressing specifies access of immediate data embedded in instruction
code. For words, two bytes (N16) in instruction code will be accessed. For bytes, one
byte (N8) in instruction code will be accessed.
Word values are expressions in the range 0–0FFFFH. Byte values are expressions in
the range 0–0FFH. However, the assembler permits values in the range covered by
both signed and unsigned expressions. For words that range is from –8000H to
+0FFFFH, and for bytes it is from –80H to +0FFH.
[Word Type]
L
A, #1234H
MOV
X1, #WORD_ARRAY_BASE
[Byte Type]
LB
A, #12H
MOVB
X1, #BYTE_ARRAY_BASE
[2]
Table Data Addressing
Table data addressing specifies access for the 64K bytes in the table segment of ROM
space as specified by TSR. This mode can be used with operands of LC, LCB, CMPC,
and CMPCB instructions.
A. Direct Table Addressing: Tadr
B. RAM Addressing Indirect Table Addressing: [**]
C. RAM Addressing Indirect Addressing with 16-Bit Base: T16 [**]
A. Direct Table Addressing
Direct table addressing specifies an address (0–0FFFFH: 64K bytes) in the table
segment specified by TSR with two bytes of instruction code. Word or byte data can be
accessed at the specified address. This addressing can be used with the four instruc-
tions LC, LCB, CMPC, and CMPCB.
