The calculation of the FREQ register value is according to the following formula:-
FREQ = (2

x
f
SC
/f
H
) /(number of pixels/line) hex
NTSC value is rounded UP from the decimal number. PAL-B, D, G, H, I and N (Argentina) are rounded DOWN. The SC_ADJ
value is derived from the adjustment needed to be added after 8 fields to ensure accuracy of the Subcarrier frequency. Note the
SC_ADJ value of 9C required for PAL-B, D, G, H, I, is different to the default state of the register.
In NTSC the NCO is reset at the end of every line, this can be disabled by setting the NCORSTD bit in SLAVE1, this allows the
VP531/VP551 to cope with line lengths that are not exactly as specified in REC656.
NOTE * For register HANC, bits 3, 4 and 5 are read only. Bits 1 and 2 are reserved. N/A = not applicable.
For register PART ID0 the VP551 value is AA
