a) Direct Port Addressing Mode:
المحدد
. For direct input operation, the data will be applied directly to destination register (AL or
AX) using (IN instruction) as shown in the following equation:
Direct Mode IN: { AX | AL}{Port Num}
■ For direct output operation a direct port number (8-bits) (0 to 255 (00-FF)) is used as
shown in the following equation:
Direct Mode OUT:: Port Num←
Example: write an assembly code to
get in the information in port 44 using
direct addressing mode.
ORG 100H
IN AX, 44H Input two byte from
port 44H, 45H to AX
{AX AL}
Example: write an assembly code to get out
the information from AX to port 44 using
direct addressing mode.
ORG 100H
Where did this number come from?
MOV AX. 030CH
RET
OUT 44H,AX
RET
0300
020d
b) Indirect Port Addressing Mode:
■ For indirect input operation, the data will be applied indirectly using Data (DX) regist
to the destination register (AL or AX) as shown in the following equation:
Indirect Mode →
