7-0

FREQL

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.

7-0

FREQ3

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.

7-0

FREQ2

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

7-0

FREQM

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).

7-0

SYSPHL

Video phase offset LSBs. This 8-bit register holds the 8 LSBs of color subcarrier

phase offset during active video.

7-0

SYSPHM

Video phase offset MSBs. This 8-bit register holds the 8 MSBs of color

subcarrier phase offset during active video.

7-0

BURPHL

Burst phase offset LSBs. This 8-bit register holds the 8 LSBs of burst phase

offset for color adjustment.

7-0

BURPHM

Burst phase offset MSBs. This 8-bit register holds the 8 MSBs of burst phase

for color adjustment.

TESTDAT

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
