MODE REGISTER 6 MR6 (MR67–MR60)
(Address (SR4–SR0) = 06H)
Mode Register 6 is an 8-bit-wide register. Figure 50 shows the
various operations under the control of Mode Register 6.
MR6 BIT DESCRIPTION
Power Up Sleep Mode Control (MR60)
After reset this bit is set to “0,” if both SCRESET/RTC and
NTSC_PAL pins are tied high, the part will power-up in sleep
mode (to facilitate low power consumption before the I
2
C is
initialized). When this bit is set to “1” (via the I
2
C), sleep mode
control passes to Mode Register 2, Bit 7.
Reserved (MR61)
A Logic “0” must be written to this bit.
Luma Autodetect Control (MR62)
This bit controls which mode of autodetect operation is being
used on the luma DAC (DAC B) on the ADV7172/ADV7173.
If this bit is set (“0”), Mode 0 is on; if this bit is set (“1”), then
Mode 1 is being used.
Composite Autodetect Control (MR63)
This bit controls which mode of autodetect operation is being
used on the composite DAC (DAC A) on the ADV7172/
ADV7173. If this bit is set (“0”), Mode 0 is on; if this bit is set
(“1”), then Mode 1 is being used.
DAC Termination Control Bit (MR64)
This bit controls the load termination resistance detected by the
autodetect functionality. If this bit is set (“0”), the autodetect
feature is used to determine if a 75
termination is present. If
this bit is set to (“1”), the autodetect feature is used to indicate
if a 150
termination is present.
Reserved (MR65)
A Logic “0” must be written to this bit.
Luma DAC Status Bit (MR66)
This bit is a read-only status bit for the autodetect feature of
the ADV7172/ADV7173 and may be read to check whether
or not the composite DAC is terminated. If this bit is set (“1”),
there is no termination; if this bit is set (“0”), the composite DAC
is terminated.
Composite DAC Status Bit (MR67)
This bit is a read only status bit for the autodetect feature of the
ADV7172/ADV7173 and may be read to check whether or not
the luma DAC is terminated. If this bit is set (“1”), there is no
termination. If this bit is set (“0”), the luma DAC is terminated.
