Description
“1”: Indicates Hsync pin is high level.
“0”: Indicates Hsync pin is low level.
“1”: Indicates Hsync input is positive polarity.
“0”: Indicates Hsync input is negative polarity.
“1”: If the H period has been changed.
Indicates the Hsync frequency in kHz.
When QUICK=”0”, HFL4 ~ HFL0 indicates the Hsync frequency in 31.25Hz unit.
When QUICK=”1”, HFL4 ~ HFL1 indicates the Hsync frequency in 62.5Hz.
