Single-Purpose Pin Descriptions
Acronym
Pin Name(s)
Description
AGND
Analog Ground
Analog Ground
B
Blue
CMOS output of the blue video signal B. Video blue
can be programmed for either polarity.
G
Green
CMOS output of the green video signal G. Video
green can be programmed for either polarity.
GND
Ground
Ground
H
SYNC
Horizontal Sync
Input pin for external horizontal synchronization
signal
IRIN
IR Capture Input
Infrared Remote capture input
OSDX1, OSDX2 On-Screen Display Dot
Clock Oscillators
These oscillator input and output pins for on-screen
display circuits are connected to an inductor and two
capacitors to generate the character dot clock. The
dot clock frequency determines the character pixel
width and phase synchronized to HSYNC
P21, P22, P23
Port 2 bits 1 - 3
Bidirectional digital port, configured to read digital
data or to send output to an attached device.
P40, P42, P43
Port 4 bit 0, bits 2 and 3
Bidirectional digital port, configured to read digital
data or to send output to an attached device.
P63
Port 6 bit 3
P63
input can be read directly at
03H
. A negative
edge event is latched to
IRQ3
. An
IRQ3
-vectored
interrupt occurs if appropriately enabled. A typical
application places the device in Stop mode when
P63
goes Low (
IRQ3
interrupt routine). When
P63
subsequently goes High, a Stop-Mode Recovery is
initiated.
R
Red
CMOS output of the red video signal R. Video red can
be programmed for either polarity.
RESET
System Reset
System reset
