FUNCTION
FUNCTION
This bit is read-only. Data written to this bit is ignored.
0 = Not vertically locked
1 = Vertically locked
This bit is read-only. Data written to this bit is ignored.
0 = Not horizontally locked
1 = Horizontally locked
This bit is read-only. Data written to this bit is ignored.
0 = Not color locked
1 = Color locked
This bit is read-only. Data written to this bit is ignored.
0 = Input video not detected on selected video input
1 = Input video detected on selected video input
This bit is set when automatic detection of the video standard is enabled, and the
HMP8116 has determined the input format of the video signal. This bit is read-only. Data
written to this bit is ignored.
0 = Video standard not determined on selected video input
1 = Video standard determined on selected video input
If this bit is a “1”, an interrupt is generated when genlock is lost.
0 = Interrupt disabled
1 = Interrupt enabled
If this bit is a “1”, an interrupt is generated when a video signal is no longer detected on
the selected video input.
0 = Interrupt disabled
1 = Interrupt enabled
If this bit is a “1”, an interrupt is generated when the Caption_ODD_A and
Caption_ODD_B or the Caption_EVEN_A and Caption_EVEN_B data registers contain
new data.
0 = Interrupt disabled
1 = Interrupt enabled
If this bit is a “1”, an interrupt is generated when the WSS_ODD_A and WSS_ODD_B or
the WSS_EVEN_A and WSS_EVEN_B data registers contain new data.
0 = Interrupt disabled
1 = Interrupt enabled
If this bit is a “1”, an interrupt is generated when teletext information is first detected at the
beginning of each field.
0 = Interrupt disabled
1 = Interrupt enabled
If this bit is a “1”, an interrupt is generated when the video standard has been automati-
cally determined.
0 = Interrupt disabled
1 = Interrupt enabled
If this bit is a “1”, an interrupt is generated at the beginning of each field.
0 = Interrupt disabled
1 = Interrupt enabled
