• Manufacturer: RENESAS [Renesas Technology Corp]

Immediate Data: Byte (8 bit) immediate data resides in instruction code. Word or longword
immediate data is not input via instruction codes but is stored in a memory table. An immediate
data transfer instruction (MOV) accesses the memory table using the PC relative addressing mode
with displacement (table 2.5).
Table 2.5
Note: @(disp, PC) accesses the immediate data.
Absolute Address: When data is accessed by absolute address, the value already in the absolute
address is placed in the memory table. Loading the immediate data when the instruction is
executed transfers that value to the register and the data is accessed in the indirect register
addressing mode (table 2.6).
Table 2.6
Note: @(disp,PC) accesses the immediate data.
