(8) CRT Output Pin Control
CRT output pins R, G, B and OUT are respectively shared with port
P52, P53, P54 and P55. When the corresponding bits in the port P5
control register (address 00CB16) are cleared to “0”, the pins are set
for CRT output ; when the bits are set to “1”, the pins function as port
P5 (general- purpose output pins).
The polarities of CRT outputs (R, G, B and OUT, as well as HSYNC
and VSYNC) can be specified by using the CRT port control register
(address 00EC16).
Use bits 0 to 4 in the CRT port control register to set the output po-
larities of HSYNC, VSYNC, R/G/B and OUT. When these bits are
cleared to “0”, a positive polarity is selected ; when the bits are set to
“1”, a negative polarity is selected.
Bits 5 to 7 in the CRT port control register are used to specify pin by
pin whether normal video signals or R-MUTE, G-MUTE, and B-
MUTE signals are output from each pin (R, G, B). When set for R-
MUTE, G-MUTE, and B-MUTE outputs, the whole background
colors of the screen become red, green, and blue.
Figure 33 shows the structure of the CRT port control register.
