Input Parameter
:
AL stores the LCD modular orders that have been written in.
Output Parameter
:
None
3.
CALL F000:F048
In this subroutine, we enter hex data in AL and get its ASCII equivalent into the cursor
position of the LCD (the position of the address counter).
Input Parameter
:
Written data (hex) is stored in AL
Output Parameter
:
None
4.
CALL F000:F04C
Read out data from cursor position of LCD (the instructed position of address counter) into
AL.
Input Parameter
:
None
Output Parameter
:
AL stores the read in data.
5.
CALL F000:F050
Read out the key-in from 8279 (execute only when the key is pressed).
Input Parameter
:
None
Output Parameter
:
The key-in value is stored in AL.
6.
CALL F000:F054
Change the numerical key-in value into ASCII code; clear the C-Flag to 0 for numerical key
otherwise set 1 for non-numerical key without changing AL value.
Input Parameter
:
The key-in value is stored in AL
Output Parameter
:
If it is a numerical key, transfer into the relative ASCII values,
store in AL and clear all flags. All non-numerical keys are set in C-Flag, and AL value changes.
7.
CALL F000:F058
Change the alphabetical key-in value into ASCII code; clear the C-Flag to 0 for alphabetical
keys otherwise set 1 for non-alphabetical keys without changing the AL value.
Input Parameter
:
The key-in value is stored in AL
Output Parameter
:
If is an alphabetical key, transfer to ASCII code to be stored in
AL and clear the C-Flags. Otherwise, the AL value will not change.
8.
CALL F000:F05C
Change the signs key-in into ASCII code, the undefined signs key will be transferred to FF to
be stored in AL, and clear the C-Flag to 0; otherwise set the flags to 1 without changing the
AL values.
Input Parameter
:
The key-in value is stored in AL.
Output Parameter
:
If it is a sign, transfer to ASCII code to be stored in AL and
clear the C-Flag, otherwise, set the C-Flags to 1 without changing AL values.
