Register
Bits 2 and 1 are the interrupt status bits:
■
■
■
The used words level of the output FIFO.
One-hot register that indicates the video mode that is selected.
Video Mode 1 Control. Bit 0 of this register is the Interlaced bit:
■
Bit 1 of this register is the sequential output control bit (only if the Allow output
of color planes in sequence compile-time parameter is enabled).
■
Video mode 1 sample count. Specifies the active picture width of the field.
Video mode 1 field 0/progressive line count. Specifies the active picture height
of the field.
Video mode 1 field 1 line count (interlaced video only). Specifies the active
picture height of the field.
Video mode 1 horizontal front porch. Specifies the length of the horizontal front
porch in samples.
Video mode 1 horizontal synchronization length. Specifies the length of the
horizontal synchronization length in samples.
Video mode 1 horizontal blanking period. Specifies the length of the horizontal
blanking period in samples.
Video mode 1 vertical front porch. Specifies the length of the vertical front porch
in lines.
Video mode 1 vertical synchronization length. Specifies the length of the vertical
synchronization length in lines.
Video mode 1 vertical blanking period. Specifies the length of the vertical
blanking period in lines.
Video mode 1 field 0 vertical front porch (interlaced video only). Specifies the
length of the vertical front porch in lines.
Video mode 1 field 0 vertical synchronization length (interlaced video only).
Specifies the length of the vertical synchronization length in lines.
Video mode 1 field 0 vertical blanking period (interlaced video only). Specifies
the length of the vertical blanking period in lines.
Video mode 1 active picture line. Specifies the line number given to the first line
of active picture.
Video mode 1 field 0 vertical blanking rising edge. Specifies the line number
given to the start of field 0's vertical blanking.
Video mode 1 field rising edge. Specifies the line number given to the end of
Field 0 and the start of Field 1.
Video mode 1 field falling edge. Specifies the line number given to the end of
Field 0 and the start of Field 1.
When bit 1 is asserted, the status update interrupt has triggered.
When bit 2 is asserted, the locked interrupt has triggered.
The interrupts stay asserted until a write of 1 is performed to these bits.
Set to 1 for interlaced. Set to a 0 for progressive.
Setting bit 1 to 1, enables sequential output from the Clocked Video Output
e.g. for NTSC. Setting bit 1 to a 0, enables parallel output from the Clocked
Video Output e.g. for 1080p.
