Description
This command is used together with Vertical Scrolling Definition (33h). These two commands describe the scrolling area
and the scrolling mode.
The Vertical Scrolling Start Address command has one parameter which describes the address of the line in the Frame
Memory that will be written as the first line after the last line of the Top Fixed Area on the display as illustrated below:
This command Start the scrolling.
When MADCTL ML=0
Example: GM=000, 132RGBx162
When Top Fixed Area = Bottom Fixed Area = 00, Vertical Scrolling Area = 162 and Vertical Scrolling Pointer SSA=’3’.

Note:
When new Pointer position and Picture Data are sent, the result on the display will happen at the next Panel Scan to avoid tearing
effect. SSA refers to the Frame Memory scan address
When new Pointer position and Picture Data, internal system works as 128x128 and maximum scan address becomes 127
internal of 161.

Restriction
Since the value of the Vertical Scrolling Start Address is absolute (with reference to the Frame Memory), it must not enter
the fixed area (defined by Vertical Scrolling Definition (33h) – otherwise undesirable image will be displayed on the Panel.
SSA[15:0] is based on 1-line unit.
SSA[15:0] =0000h, 0001h, 0002h, 003h, …, 00A1h
