HFPOL - HFLBK input polarity select
1 (set)
Horizontal yback signal at HFLBK is active low.
0 (clear) –
Horizontal yback signal at HFLBK is active high.
HTPOL - FBKG output polarity select
1 (set)
HTONE (half tone) output pin is active low.
0 (clear) –
HTONE (half tone) output pin is active high.
The HTONE output pin is shared with port pin PF3. If HTONE is disabled, HTPOL will have no
effect.
FBPOL - FBKG output polarity select
1 (set)
FBKG (fast blanking) output pin is active low.
0 (clear) –
FBKG (fast blanking) output pin is active high.
RGBPOL - RGB output polarity select
1 (set)
RBG output pins are active low.
0 (clear) –
RGB output pins are active high.
IPOL - I output polarity select
1 (set)
I (intensity) output pin is active low.
0 (clear) –
I (intensity) output pin is active high.

Frame Control 3 and Status Register
Bits 7 to 5 are control bits whereas bits 4 to 0 are status bits associated with interrupt. A status bit
is cleared by writing a 0 to that bit. Care must be taken while clearing a status bit: make sure the
