14-0
The value programmed in this register indicates the end
line number of the trailing edge of the user-programmed
V Sync signal USER4_V. For interlaced output
standards, this value corresponds to the odd field line
number.
NOTE: The value programmed in this register must not
exceed the maximum number of lines per field of the
outgoing standard.

Polarity_4 - Use this bit to invert the polarity of the final
USER4 signal.
By default, the polarity of the user programmed signals
is active LOW. The polarity may be switched to active
HIGH by setting this bit LOW.

AND_4 - logical operator: USER4_H AND USER4_V
Set this bit HIGH to output a signal that is only active
when both USER4_H and USER4_V are active.
When this bit is HIGH, bit 1 and bit 0 of this register will
be ignored.
Reference:
Section 3.8.3 on page 59
R/W

6Ah
1
OR_4 - logical operator: USER4_H OR USER4_V
Set this bit HIGH to output a signal that is active
whenever USER4_H or USER4_V are active.
When this bit is HIGH bit 0 of this register will be
ignored.
Reference:
Section 3.8.3 on page 59
R/W

6Ah
0
XOR_4 - logical operator: USER4_H XOR USER4_V
Set this bit HIGH to output a signal with the following
attributes: Signal becomes active when either
USER4_H or USER4_V is active. Signal is inactive
when USER4_H and USER4_V are both active or both
inactive.
Reference:
Section 3.8.3 on page 59

Ext_Audio_Mode
81h
15-0
Set this register to 20C1h to enable the Extended Audio
Mode of the device.
To fully enable this mode, VID_STD[5:0] must be set to
4d, and the F_Lock_Mask and V_Lock_Mask bits [4:3]
of register address 16h must be set to 1.
NOTE: Once this register is programmed, it must be
updated using bit 6 of register 16h.
