1. Ranges will be based on the line and pixel ranges programmed by the Host
Interface; or
2. In the absence of user-programmed calculation ranges, ranges will be determined
from the received TRS timing information.
The registers available to the Host Interface for programming EDH calculation ranges
include Active Picture and Full Field line start and end positions for both fields.
Table 4-13 shows the relevant registers, which default to 'zero' after device reset.
If any or all of these register values are zero, then the EDH CRC calculation ranges will
be determined from the Flywheel generated H signal. The first active and full field pixel
will always be the first pixel after the SAV TRS code word. The Last Active and Full Field
pixel will always be the last pixel before the start of the EAV TRS code words.
