MODE REGISTER 3 MR3 (MR37–MR30)
(Address (SR4–SR0) = 03H)
Mode Register 3 is an 8-bit-wide register. Figure 47 shows the
various operations under the control of Mode Register 3.
MR3 BIT DESCRIPTION
Revision Code (MR31–MR30)
This bit is read-only and indicates the revision of the device.
VBI Pass-Through Control (MR32)
This bit determines whether or not data in the vertical blanking
interval (VBI) is output to the analog outputs or blanked. Note
that this condition is also valid in timing slave mode 0.
Teletext Enable (MR33)
This bit must be set to “1” to enable teletext data insertion on
the TTX pin.
Teletext Mode Control (MR34)
This bit enables switching of the teletext request signal from a
continuous high signal (MR34 = “0”) to a bit wise request
signal (MR34 = “1”).
Closed Captioning Field Control (MR36–MR35)
These bits control the fields that closed captioning data is dis-
played on. Closed captioning information can be displayed on
an odd field, even field or both fields.
Active Video Filter Switching (MR37)
This bit, controls the filter mode applied outside the active
video portion of the line. This filter ensures that the sync rise
and fall times are always on spec regardless of which luma filter
is selected.
