MOTOROLA ANALOG IC DEVICE DATA
to prevent the PIP from interfering with the main picture
sync pulses.
PIP Y Position Register
Sub–address = 07h
Y Position Bits (YPS0–5) – D0–D5
Moves the PIP start position from the top to the bottom
edge of the display in 64 steps. There is protection circuitry to
prevent the PIP from interfering with the main picture sync
pulses.
PIP Chroma Level Register
Sub–address = 08h
Chroma (C0–5) – D0–D5
The color of the PIP can be adjusted to suit viewer
preference by setting the value stored in these bits. A total of
64 steps varies the color from no color to maximum. This
control acts in conjunction with the auto phase control.
PIP Tint Level Register
Sub–address = 09h
Tint (T0–5) – D0–D5
An auto phase control compares the main color burst to
the internally generated pseudo color burst so that the tints
are matched. In addition to this, the tint of the PIP can be
varied
±
10
°
in a total of 64 steps by changing the value of
these bits to suit viewer preference.
PIP Luma Delay Register
Sub–address = 0Ah
Y Delay (YDL0–2) – D0–D2
Since the Chroma passes through a bandpass filter and
the color decoder, it is delayed with respect to the Luma
signal. Therefore, to time match the Luma and Chroma these
bits are set to a single value determined to be correct in the
application.
Pip Fill/Test Register
Sub–address = 0Ch
PIP Fill Bits (PIPFILL0–1) – D0–D1
May be used to fill the PIP with one of three selectable
solid colors
Test Register Bits (INTC0 and MACR0) – D6–D7
Used for production test only.
