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 The off level HSYNC input is high.
= 0 The off level HSYNC input is low.
Voff* = 1 The off level VSYNC input is high.
= 0 The off level VSYNC input is low.
*Hoff and Voff are valid when Hpre=0 or Vpre=0.
HCNTH (r) : High bits of H-Freq counter.
Hovf = 1 H-Freq counter is overflowed, this bit is cleared by H/W when condition removed.
HF13 - HF8 : 6 high bits of H-Freq counter.
HCNTL (r) : Low byte of H-Freq counter.
VCNTH (r) : High bits V-Freq of counter.
Vovf = 1 V-Freq counter is overflowed, this bit is cleared by H/W when condition removed.
VF11 - 8 :
4 high bits of V-Freq counter.
VCNTL (r) : Low byteV-Freq counter.
HVCTR0 (w) : H/V SYNC processor control register 0.
C1, C0 = 1,1 Selects CVSYNC as the polarity, freq and VBLANK source.
= 1,0 Selects VSYNC as the polarity, freq and VBLANK source.
= 0,0 Disables composite function.
= 0,1 H/W auto switches 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.
