NAME

DESCRIPTION

7

OSDEN

The OSD circuit is active when this bit is set to logic 1. The outputs of R, G, B and FB

will be high impedance when OSD is disabled.

6

BSEN

The bordering or shadowing effect is enabled when this bit is set to logic 1.

5

SHSE

The shadowing of characters is selected if this bit is set to logic 1, otherwise bordering

of characters is chosen.

0

FBC

This bit defines the output configuration of the FB pin. If this bit is set to logic 0, then the

output of FB will be logic HIGH when displaying character or window, otherwise the

output of FB is logic HIGH only when displaying characters.
