FBKGCi - FBKG (Fast Blanking) pin active select
FBKGCi bit controls the FBKG output pin of the OSD during row i display. If FBKGCi is clear, FBKG
output pin is active during both character dots and background dots of row i. If FBKGCi is set,
FBKG output pin is active only where character dots exist in the character dot matrix (including
bordering or shadowing dots). The FBKG and HTONE pins may be used to create transparent
background effects for OSD displays.
