(35) Relation between each setting and COM / display RAM
The COM port number corresponds to Y address of display RAM by SHIFT command, LCD duty
command, common display start position command and display start line setting command.
When display start address was set to “0”.
According to LCD duty and display start common line address, the port of COM line and
display RAM address ( MY ) is changed by 15 line unit.
When SHIFT register is set to “0” common line shift to upward direction, and when the value is
“1”, common line shift to downward direction. When display start address (LA
6
~LA
0
) is set to
“0”, the “MY” corresponds to starting position is “0”. The MY shift upward direction as display
goes on.
In any case, COMI
0
=MY80, COMI
1
=MY81 .
When display start line was set except for “0”
According to LCD duty and display start common line address, the port of COM line and
display RAM address, MY is changed by 15 line unit.
When SHIFT register is set to “0” common line shift to upward direction, and when the value is
“1”, common line shift to downward direction. When display start address (LA
6
~LA
0
) is set to
except for “0”, the “MY” corresponds to starting position is shift by the amount of set value.
The MY shift upward direction as display goes on but MY is set to “0” after MY=79.
In any case, COMI
0
=MY80, COMI
1
=MY81 .
