Pre-Amplifier Interface Registers (Continued)
Horizontal Front Porch Duration:
H_FP1 (0x8581)
H_FP0 (0x8580)
Reserved
Horizontal Front Porch Duration
XXXXX
HFP[10:0]
Bit 10–0
This is an 11-bit wide register that records the lowest measured value of the horizontal front porch
during video detect. When no video is detected, this register should return a value of zero. Once
measurement is completed and the auto size enable bit has cleared itself back to 0, the measured
data is ready to be read by the microcontroller. Reading this register before that may give
erroneous results. This register resets to default values, ready to record new measured values
when the auto size enable bit is set again.
Horizontal Flyback or Sync Duration:
HF_S1 (0x8583)
HF_S0 (0x8582)
Reserved
Horizontal Flyback or Sync Duration
XXXXXX
HFL_HS[9:0]
Bits 9–0
This is a 10-bit wide register that records the measured value of the horizontal flyback or sync
during video detect. When no video is detected, this register should return a value of zero. Once
measurement is completed and the auto size enable bit has cleared itself back to 0, the measured
data is ready to be read by the microcontroller. Reading this register before that may give
erroneous results. This register resets to default values, ready to record new measured values
when the auto size enable bit is set again.
Horizontal Back Porch Duration:
HF_BP1 (0x8585)
HF_BP0 (0x8584)
Reserved
Horizontal Back Porch Duration
XXXXX
HBP[10:0]
Bits 10–0
This is an 11-bit wide register that records the lowest measured value of the horizontal back porch
during video detect. When no video is detected, the sum of this register and the horizontal flyback
or sync should be within 1 pixel of the total number of pixels per line. Once measurement is
completed and the auto size enable bit has cleared itself back to 0, the measured data is ready to
be read by the microcontroller. Reading this register before that may give erroneous results. This
register resets to default values, ready to record new measured values when the auto size enable
bit is set again.
Vertical Front Porch Duration:
V_FP1 (0x8587)
V_FP0 (0x8586)
Reserved
Vertical Front Porch Duration
XXXXX
VBP[10:0]
Bits 10–0
This is an 11-bit wide register that records the lowest measured value of the vertical front porch in
terms of horizontal line periods during video detect. When no video is detected, this register should
return a value of zero. Once measurement is completed and the auto size enable bit has cleared
itself back to 0, the measured data is ready to be read by the microcontroller. Reading this register
before that may give erroneous results. This register resets to default values, ready to record new
measured values when the auto size enable bit is set again.
Vertical Flyback or Sync Duration:
V_SYN_D (0x8588)
Vertical Flyback or Sync Duration
VSYNC[7:0]
