Nothing is assigned. In an attempt to write to this bit, write “0.”
The value, if read, turns out to be indeterminate.
Notes 1: Tc is OSD clock cycle divided in pre-divide circuit
2: H is HSYNC
3: This character size is available only in Layer 2. At this time, set layer 1’s
pre-divide ratio = ✕ 2, layer 1’s horizontal dot size = 1Tc.
4: In OSDL and OSDP modes, 1.5Tc size cannot be used.
