Parameter Storage
The current parameter settings can be stored to one of seven EEPROM registers for the present video
standard by setting SWA to position E and setting SWB to any value from 1 to 7. The storage to EEPROM
occurs when SWA is then moved OUT of position E. If SWB is set to any value except 1-7, moving SWA
out of position E will NOT result in parameter storage to EEPROM. Note that separate storage locations
exist for 625 and 525 line parameters (7 for each). 7 locations are also reserved for 270Mbps streams
which cannot be identified as 525 or 625 line signals (for compatibility with future 270Mbit streams).
Parameter Recall
Stored parameter settings can be recalled from one of seven EEPROM registers for the present video
standard by setting SWA to position F and setting SWB to any value from 1 to 7. As SWB is changed, the
the settings are recalled from the corresponding EEPROM register. On power up the module automatically
configures the module to the settings in effect when power was lost.
