Function
Subcarrier frequency 4th byte (LSBs). This 8-bit register holds the LSB (bits
7-0) of the 32-bit subcarrier frequency value (non-genlock modes). The next
eight most significant bits are held in Register 21.
Subcarrier frequency 3rd byte. This 8-bit register holds bits 15:8 of the
subcarrier frequency value (non-genlock modes). The next eight most
significant bits are held in Register 22.
Subcarrier frequency 2nd byte. This 8-bit register holds bits 23-16 of the
subcarrier frequency value (non-genlock modes). The eight MSBs are held in
Register 23.
Subcarrier frequency 1st byte (MSBs). This 8-bit register holds the MSBs (bits
31-24) of the 32-bit subcarrier frequency value (non-genlock modes).
Video phase offset LSBs. This 8-bit register holds the 8 LSBs of color subcarrier
phase offset during active video.
Video phase offset MSBs. This 8-bit register holds the 8 MSBs of color
subcarrier phase offset during active video.
Burst phase offset LSBs. This 8-bit register holds the 8 LSBs of burst phase
offset for color adjustment.
Burst phase offset MSBs. This 8-bit register holds the 8 MSBs of burst phase
for color adjustment.
Function
Test data input/output. This 8-bit register holds MSBs or LSBs, as determined
by the Test Control Register. This control address does not auto-increment
during read or write operations. To exit the test mode, reset the Control
Register pointer by setting A
Function
Mask register. This 8-bit register holds an 8-bit word that is logically ANDed with
the incoming data presented to the three CLUTs in color-index mode. This
register is a write-only register.
Function
Y-component register. This register holds the contents of the luminance value
before the Sync and Blank Insert circuitry of the encoder. Loading the Control
Register pointer with 60
