Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Separation Width
The low-level pulse width of the separation pulse
for the CSYNC signal should be set in dot clock
units.
The value set should be smaller than 1/2 the HC
bits in HCR.
To enable this setting, bit 1 of the CSY bits in
DSMR should be set to 1.
