The following are example register settings while external synchronization signals HSYNC and VSYNC
are used:
Same as internal synchronization signals:
HTN
HTND
VDS
VDE
VDSD
VDED
= 0x05,
= 0x01,
= 0x1B,
= 0xFC,
= 0x3B,
= 0x5B.
Different from settings using internal synchronization signals:
HDS
HDE
HDSD
HDED
= 0x14,
= 0xB4,
= 0x34,
= 0x54.
Not relevant registers:
HC,
VC,
HSW,
VSW.
The display shows the same picture with the selected external synchronization signals HSYNC and
VSYNC as in case of internal synchronization signal described before.
