bits 25–16 Picture-in-Picture X End Position Bits [9:0]
These bits determine the X end position of the Picture-in-Picture sub-window in relation
to the origin of the panel. Due to the S1C38000 SwivelView feature, the X end position
may not be a horizontal position value (only true in 0° and 180° SwivelView). For
further information on defining the value of the X End Position register, see Section
15.11, “Picture-in-Picture Plus” on page 151.
The register is also incremented differently based on the SwivelView orientation. For 0°
and 180° SwivelView the X end position is incremented by x pixels where x is relative
to the current color depth.
For 90° and 270° SwivelView, the X end position is incremented in 1 line increments.
Depending on the color depth, some of the higher bits in this register are unused because
the maximum horizontal display width is 1024 pixels.
Notes: These bits have no effect unless the Picture-in-Picture Enable bit is set to 1 (LCD[10h]
bit 19).
The effect of LCD[58h] and LCD[5Ch] takes place only after LCD[5Ch] is written and at
the next vertical non-display period.
bits 9–0
Picture-in-Picture X Start Position Bits [9:0]
These bits determine the X start position of the Picture-in-Picture sub-window in
relation to the origin of the panel. Due to the S1C38000 SwivelView feature, the X start
position may not be a horizontal position value (only true in 0° and 180° SwivelView).
For further information on defining the value of the X Start Position register, see Section
15.11, “Picture-in-Picture Plus” on page 151.
The register is also incremented differently based on the SwivelView orientation. For 0°
and 180° SwivelView the X start position is incremented by x pixels where x is relative
to the current color depth.
For 90° and 270° SwivelView, the X start position is incremented in 1 line increments.
Depending on the color depth, some of the higher bits in this register are unused because
the maximum horizontal display width is 1024 pixels.
Notes: These bits have no effect unless the Picture-in-Picture Enable bit is set to 1 (LCD[10h]
bit 19).
The effect of LCD[58h] and LCD[5Ch] takes place only after LCD[5Ch] is written and at
the next vertical non-display period.
