HVSTUS (r) : The status of polarity, present and static level for HSYNC and VSYNC.
CVpre = 1 → The extracted CVSYNC is present.
= 0 → The extracted CVSYNC is not present.
Hpol = 1 → HSYNC input is positive polarity.
= 0 → HSYNC input is negative polarity.
Vpol = 1 → VSYNC (CVSYNC) is positive polarity.
= 0 → VSYNC (CVSYNC) is negative polarity.
Hpre = 1 → HSYNC input is present.
= 0 → HSYNC input is not present.
Vpre = 1 → VSYNC input is present.
= 0 → VSYNC input is not present.
Hoff* = 1 → HSYNC input's off level is high.
= 0 → HSYNC input's off level is low.
Voff* = 1 → VSYNC input's off level is high.
= 0 → VSYNC input's off level is low.
*Hoff and Voff are valid when Hpre=0 or Vpre=0.
HCNTH (r) : H-Freq counter's high bits.
Hovf = 1 → H-Freq counter is overflow, this bit is clear by H/W when condition removed.
HF13 - HF8 : 6 high bits of H-Freq counter.
HCNTL (r) : H-Freq counter's low byte.
VCNTH (r) : V-Freq counter's high bits.
Vovf = 1 → V-Freq counter is overflow, this bit is clear by H/W when condition removed.
VF11 - 8 :
4 high bits of V-Freq counter.
VCNTL (r) : V-Freq counter's low byte.
HVCTR0 (w) : H/V SYNC processor control register 0.
C1, C0 = 1,1 → Select CVSYNC as the polarity, freq and VBLANK source.
= 1,0 → Select VSYNC as the polarity, freq and VBLANK source.
= 0,0 → Disable composite function.
= 0,1 → H/W auto switch to CVSYNC when CVpre=1 and VSpre=0.
NoHins = 1 → HBLANK has no insert pulse in composite mode.
= 0 → HBLANK has insert pulse in composite mode.
HBpl = 1 → negative polarity HBLANK output.
= 0 → positive polarity HBLANK output.
VBpl = 1 → negative polarity VBLANK output.
= 0 → positive polarity VBLANK output.
HVCTR2 (w) : Self-test pattern generator control.
Selft = 1 → enable generator.
= 0 → disable generator.
STF1,STF0 = 1,1 → 95.2KHz(horizontal)/72Hz(vertical) output selected.
