MC44463
I2C REGISTER DESCRIPTIONS
Base write address = 26h
Base read address = 27h
Read Register
There are two active bits in the single read byte available
from the MC44463 as follows:
Write Vertical Indicator (WVI0) â D7
When 0 indicates that the write operation specified by the
last I2C command has been completed.
PIP Sync Detect Bit (PSD0) â D1
When 0 indicates that the PIP video H pulses are present
and the horizontal timebase oscillator is within acceptable
limits.
Write Registers
Read Start Position/Write Start Position Registers
Subâaddress = 00h
Write Raster Position Start Bits (WPS0â2) â D0âD2
Establishes the horizontal beginning of the PIP and its
black level measurement gate. This beginning may be varied
by approximately 3.0 µs. The position of this pulse may be
observed through the Multi Test Pin 30 (See Test Mode
Register Subâaddress 03h).
Read Raster Position Bits (RPS0â3) â D4âD7
Establishes the clamp gate position for the black level
reference for the main picture. This position may be varied by
approximately 5.0 µs. The position of this pulse may be
observed through the Multi Test Pin 30 (See Test Mode
Register Subâaddress 03h).
Pip Switch Delay/Vertical Filter Register
Subâaddress = 01h
PIP Switch Delay Bits (PSD0â3) â D0âD3
Delays the start of PIP on time relative to the PIP picture.
These bits are used to center the PIP border and PIP picture
in the horizontal direction.
Vertical Filter Bit (VFON) â D4
When the filter is activated (VFON = 1) a three line
weighted average is taken to provide the data stored in the
field memory.
Border Color Register
Subâaddress = 02h
Border Color Bits (BC0â2) â D0âD2
These Bits control the color of the border. Note that when
using one of the saturated border colors it is possible to get
objectionable dot crawl at the edge of the border in some TVs
unless appropriate comb filtering is used in the TV circuitry.

Test Mode/Main Vertical and Horizontal Polarity Register
Subâaddress = 03h
Internal Test Mode Register (ITM0â2) â D0âD2
Sets the Multi Test Pin output to provide one of several
internal signals for test and production alignment. Also
controls the test memory address counter.
