(15) Partial in (PTLIN) Command: 1 Parameter: 2
This command and succeeding parameters specify the partial display area. This command is used to turn on partial
display of the screen (dividing screen by lines) in order to save power. Since S1D15G10 processes the liquid crystal
display signals on 4-line basis (block basis), the display and non-display areas are also specified on 4-bit line (block
basis).
*: Invalid bits irrelevant with the operation.
A block address that can be specified for the partial display must be the displayed one (don’t try to specify an address
not to be displayed when scrolled).
When the partial display mode is turned on, following state is introduced to S1D15G10 in the non-display area:
* LOW is output to DOFF pin.
* All COM pins output V
C
.
* All SEG pins output V
1
or MV
1
.
SEG output is forced to V
1
or MV
1
depending on state of FR in the last display line. When FR is HIGH, V
1
is output
and when FR is LOW, MV
1
is output. Phase of FR is constantly reversed at start of a frame.

(17) Read modify write in (RMWIN) Command: 1 Parameter: 0
This command is used along with the column address set command, page address set command and read modify write
out command. This function is used when frequently modifying data to specify a specific display area such as blinking
cursor. First set a specific display area using the column and page address commands. Then, enter this command to
set the column and page addresses at the start address of the specific area. When this operation is complete, the column
(page) address won’t be modified by the display data read command. It is incremented only when the display data write
command is used. You can cancel this mode by entering the read modify write out or any other command.
