Shadowing modes determined by bits SHM2 to SHM0 (register OSMOD) and Sh (register OSAT)
Note
1.
The mode names are based on the position of an apparent light source, ranging from the lower left (South-west)
clockwise to the lower right (South-east); see Fig.8.

Description of OSORG bits (note 1)
Notes
1.
Neither the Hstart nor Vstart parameter is affected by the D line attribute that is used to display double-sized
characters.
Counting variations in Wc, there may be 17 to 143 VCLK clock cycles from the end of HSYNC to the start of the first
character of each row.
Subsequent character rows occur directly below the first, such that the last scan line of one row is directly followed
by the first scan line of the next row. Successive New Line characters (with or without the Short Row designation)
can be used to vertically separate text rows on the screen.

DESCRIPTION

HS4 to HS0
HStart field; defines the horizontal start position of all the on-screen character rows, as
approximately a multiple of 4 VCLK clock cycles. Active display begins after the trailing
edge of HSYNC at the position:
Where (HStart) is the decimal value of bits (HS4 to HS0); note 2.
VStart field; defines the vertical start position of the first on-screen character row, as
approximately a multiple of 4 HSYNC pulses. Active display begins after the field’s time
reference point (a range of 3 to 31)at the position:
2 to 0
VS2 to VS0
Where (VStart) is the decimal value of bits (VS2 to VS0); note 3.
