PWM9 to PWM0
: 8-bit Pulse Width Modulation outputs 9 to 0. Pin 41 and 42 can
also be used as the output pin of the test pattern display PATOUT and clamping out
signal CLAMP respectively; PATOUT and CLAMP always have the higher priority.
Alternative function general I/O ports;
Port 3: P3.1 to P3.0
and
Port 2: P2.7 to P2.0
.
Oscillator input pin for system clock.
Oscillator output pin for system clock.
Digital power supply (+5 V).
Digital ground.
Horizontal sync input pin. During OTP programming it is used as the program pulse
input (PROG).
Horizontal sync output pin; alternative function: general I/O port P1.5.
Composite sync input pin; alternative function: general I/O port P1.6.
Vertical sync input pin. During OTP programming it is used as output strobe (OE).
Vertical sync output pin; alternative function: general I/O port P1.4.
18 to 25 Port 0: general I/O ports; capability to drive LED.
