9.1.3 Field Offset Canceller
This offset value is totalled after the gain correction. Its purpose is mainly to cancel the differ-
ential offset between all channels (see refer to
D2 Register: Fine horizontal
D3 Register: Fine vertical
The Field offset values are in two’s complement.
Note: During the vertical retrace, the field offset canceller values are the only correction values available
9.2 DYNAMIC VALUES
Dynamic values are stored in register addresses 00 to CF in the three red, blue and green
banks. For their allocation, refer to
on page
The dynamic values can be adjusted from -512 to +511
9.3 INTERLACE
The interlace correction value is defined by the ICV[5:0] bits in the DA register.
This value is added to each convergence value in the field chosen by the IFA bit in the DA reg-
ister.
The interlace mode is enabled by the IIE bit in the DA register.
